#
#	This means only your local clients are allowed to fetch

#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#Default:
# miss_access allow all

#  TAG: reply_body_max_size	size [acl acl...]
#	This option specifies the maximum size of a reply body. It can be
#	used to prevent users from downloading very large files, such as
#	MP3's and movies. When the reply headers are received, the
#	reply_body_max_size lines are processed, and the first line where
#	all (if any) listed ACLs are true is used as the maximum body size
#	for this reply.
#
#	This size is checked twice. First when we get the reply headers,
#	we check the content-length value.  If the content length value exists
#	and is larger than the allowed size, the request is denied and the
#	user receives an error message that says "the request or reply
#	is too large." If there is no content-length, and the reply
#	size exceeds this limit, the client's connection is just closed
#	and they will receive a partial reply.
#
#	WARNING: downstream caches probably can not detect a partial reply
#	if there is no content-length header, so they will cache
#	partial responses and give them out as hits.  You should NOT
#	use this option if you have downstream caches.
#
#	WARNING: A maximum size smaller than the size of squid's error messages
#	will cause an infinite loop and crash squid. Ensure that the smallest
#	non-zero value you use is greater that the maximum header size plus
#	the size of your largest error page.
#
#	If you set this parameter none (the default), there will be
#	no limit imposed.
#
#	Configuration Format is:
#		reply_body_max_size SIZE UNITS [acl ...]
#	ie.
#		reply_body_max_size 10 MB
#
#Default:
# none


# SSL OPTIONS
# -----------------------------------------------------------------------------

#  TAG: ssl_unclean_shutdown
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ssl option
#
#	Some browsers (especially MSIE) bugs out on SSL shutdown
#	messages.
#Default:
# ssl_unclean_shutdown off

#  TAG: ssl_engine
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ssl option
#
#	The OpenSSL engine to use. You will need to set this if you
#	would like to use hardware SSL acceleration for example.
#Default:
# none

#  TAG: ssl_bump
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ssl option
#
#	This ACL controls which CONNECT requests to an http_port
#	marked with an sslBump flag are actually "bumped". Please
#	see the sslBump flag of an http_port option for more details
#	about decoding proxied SSL connections.
#
#	By default, no requests are bumped.
#
#	See also: http_port sslBump
#
#	This clause only supports fast acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#
#
#	# Example: Bump all requests except those originating from localhost and
#	# those going to webax.com or example.com sites.
#
#	acl localhost src 127.0.0.1/32
#	acl broken_sites dstdomain .webax.com
#	acl broken_sites dstdomain .example.com
#	ssl_bump deny localhost
#	ssl_bump deny broken_sites
#	ssl_bump allow all
#Default:
# none

#  TAG: sslproxy_cert_error
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ssl option
#
#	Use this ACL to bypass server certificate validation errors.
#
#	For example, the following lines will bypass all validation errors
#	when talking to servers located at 172.16.0.0/16. All other
#	validation errors will result in ERR_SECURE_CONNECT_FAIL error.
#
#		acl BrokenServersAtTrustedIP dst 172.16.0.0/16
#		sslproxy_cert_error allow BrokenServersAtTrustedIP
#		sslproxy_cert_error deny all
#
#	This clause only supports fast acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#	Using slow acl types may result in server crashes
#
#	Without this option, all server certificate validation errors
#	terminate the transaction. Bypassing validation errors is dangerous
#	because an error usually implies that the server cannot be trusted and
#	the connection may be insecure.
#
#	See also: sslproxy_flags and DONT_VERIFY_PEER.
#
#	Default setting:  sslproxy_cert_error deny all
#Default:
# none

#  TAG: sslpassword_program
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ssl option
#
#	Specify a program used for entering SSL key passphrases
#	when using encrypted SSL certificate keys. If not specified
#	keys must either be unencrypted, or Squid started with the -N
#	option to allow it to query interactively for the passphrase.
#Default:
# none

# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
# -----------------------------------------------------------------------------

#  TAG: cache_peer
#	To specify other caches in a hierarchy, use the format:
#
#		cache_peer hostname type http-port icp-port [options]
#
#	For example,
#
#	#                                        proxy  icp
#	#          hostname             type     port   port  options
#	#          -------------------- -------- ----- -----  -----------
#	cache_peer parent.foo.net       parent    3128  3130  default
#	cache_peer sib1.foo.net         sibling   3128  3130  proxy-only
#	cache_peer sib2.foo.net         sibling   3128  3130  proxy-only
#	cache_peer example.com          parent    80       0  no-query default
#	cache_peer cdn.example.com      sibling   3128     0
#
#	      type:	either 'parent', 'sibling', or 'multicast'.
#
#	proxy-port:	The port number where the peer accept HTTP requests.
#			For other Squid proxies this is usually 3128
#			For web servers this is usually 80
#
#	  icp-port:	Used for querying neighbor caches about objects.
#			Set to 0 if the peer does not support ICP or HTCP.
#			See ICP and HTCP options below for additional details.
#
#
#	==== ICP OPTIONS ====
#
#	You MUST also set icp_port and icp_access explicitly when using these options.
#	The defaults will prevent peer traffic using ICP.
#
#
#	no-query	Disable ICP queries to this neighbor.
#
#	multicast-responder
#			Indicates the named peer is a member of a multicast group.
#			ICP queries will not be sent directly to the peer, but ICP
#			replies will be accepted from it.
#
#	closest-only	Indicates that, for ICP_OP_MISS replies, we'll only forward
#			CLOSEST_PARENT_MISSes and never FIRST_PARENT_MISSes.
#
#	background-ping
#			To only send ICP queries to this neighbor infrequently.
#			This is used to keep the neighbor round trip time updated
#			and is usually used in conjunction with weighted-round-robin.
#
#
#	==== HTCP OPTIONS ====
#
#	You MUST also set htcp_port and htcp_access explicitly when using these options.
#	The defaults will prevent peer traffic using HTCP.
#
#
#	htcp		Send HTCP, instead of ICP, queries to the neighbor.
#			You probably also want to set the "icp-port" to 4827
#			instead of 3130.
#
#	htcp-oldsquid	Send HTCP to old Squid versions.
#
#	htcp-no-clr	Send HTCP to the neighbor but without
#			sending any CLR requests.  This cannot be used with
#			htcp-only-clr.
#
#	htcp-only-clr	Send HTCP to the neighbor but ONLY CLR requests.
#			This cannot be used with htcp-no-clr.
#
#	htcp-no-purge-clr
#			Send HTCP to the neighbor including CLRs but only when
#			they do not result from PURGE requests.
#
#	htcp-forward-clr
#			Forward any HTCP CLR requests this proxy receives to the peer.
#
#
#	==== PEER SELECTION METHODS ====
#
#	The default peer selection method is ICP, with the first responding peer
#	being used as source. These options can be used for better load balancing.
#
#
#	default		This is a parent cache which can be used as a "last-resort"
#			if a peer cannot be located by any of the peer-selection methods.
#			If specified more than once, only the first is used.
#
#	round-robin	Load-Balance parents which should be used in a round-robin
#			fashion in the absence of any ICP queries.
#			weight=N can be used to add bias.
#
#	weighted-round-robin
#			Load-Balance parents which should be used in a round-robin
#			fashion with the frequency of each parent being based on the
#			round trip time. Closer parents are used more often.
#			Usually used for background-ping parents.
#			weight=N can be used to add bias.
#
#	carp		Load-Balance parents which should be used as a CARP array.
#			The requests will be distributed among the parents based on the
#			CARP load balancing hash function based on their weight.
#
#	userhash	Load-balance parents based on the client proxy_auth or ident username.
#
#	sourcehash	Load-balance parents based on the client source IP.
#
#	multicast-siblings
#			To be used only for cache peers of type "multicast".
#			ALL members of this multicast group have "sibling"
#			relationship with it, not "parent".  This is to a mulicast
#			group when the requested object would be fetched only from
#			a "parent" cache, anyway.  It's useful, e.g., when
#			configuring a pool of redundant Squid proxies, being
#			members of the same multicast group.
#
#
#	==== PEER SELECTION OPTIONS ====
#
#	weight=N	use to affect the selection of a peer during any weighted
#			peer-selection mechanisms.
#			The weight must be an integer; default is 1,
#			larger weights are favored more.
#			This option does not affect parent selection if a peering
#			protocol is not in use.
#
#	basetime=N	Specify a base amount to be subtracted from round trip
#			times of parents.
#			It is subtracted before division by weight in calculating
#			which parent to fectch from. If the rtt is less than the
#			base time the rtt is set to a minimal value.
#
#	ttl=N		Specify a IP multicast TTL to use when sending an ICP
#			queries to this address.
#			Only useful when sending to a multicast group.
#			Because we don't accept ICP replies from random
#			hosts, you must configure other group members as
#			peers with the 'multicast-responder' option.
#
#	no-delay	To prevent access to this neighbor from influencing the
#			delay pools.
#
#	digest-url=URL	Tell Squid to fetch the cache digest (if digests are
#			enabled) for this host from the specified URL rather
#			than the Squid default location.
#
#
#	==== ACCELERATOR / REVERSE-PROXY OPTIONS ====
#
#	originserver	Causes this parent to be contacted as an origin server.
#			Meant to be used in accelerator setups when the peer
#			is a web server.
#
#	forceddomain=name
#			Set the Host header of requests forwarded to this peer.
#			Useful in accelerator setups where the server (peer)
#			expects a certain domain name but clients may request
#			others. ie example.com or www.example.com
#
#	no-digest	Disable request of cache digests.
#
#	no-netdb-exchange
#			Disables requesting ICMP RTT database (NetDB).
#
#
#	==== AUTHENTICATION OPTIONS ====
#
#	login=user:password
#			If this is a personal/workgroup proxy and your parent
#			requires proxy authentication.
#
#			Note: The string can include URL escapes (i.e. %20 for
#			spaces). This also means % must be written as %%.
#
#	login=PROXYPASS
#			Send login details received from client to this peer.
#			Authentication is not required, nor changed.
#
#			Note: This will pass any form of authentication but
#			only Basic auth will work through a proxy unless the
#			connection-auth options are also used.
#
#	login=PASS	Send login details received from client to this peer.
#			Authentication is not required by this option.
#			If there are no client-provided authentication headers
#			to pass on, but username and password are available
#			from either proxy login or an external ACL user= and
#			password= result tags they may be sent instead.
#
#			Note: To combine this with proxy_auth both proxies must
#			share the same user database as HTTP only allows for
#			a single login (one for proxy, one for origin server).
#			Also be warned this will expose your users proxy
#			password to the peer. USE WITH CAUTION
#
#	login=*:password
#			Send the username to the upstream cache, but with a
#			fixed password. This is meant to be used when the peer
#			is in another administrative domain, but it is still
#			needed to identify each user.
#			The star can optionally be followed by some extra
#			information which is added to the username. This can
#			be used to identify this proxy to the peer, similar to
#			the login=username:password option above.
#
#	connection-auth=on|off
#			Tell Squid that this peer does or not support Microsoft
#			connection oriented authentication, and any such
#			challenges received from there should be ignored.
#			Default is auto to automatically determine the status
#			of the peer.
#
#
#	==== SSL / HTTPS / TLS OPTIONS ====
#
#	ssl		Encrypt connections to this peer with SSL/TLS.
#
#	sslcert=/path/to/ssl/certificate
#			A client SSL certificate to use when connecting to
#			this peer.
#
#	sslkey=/path/to/ssl/key
#			The private SSL key corresponding to sslcert above.
#			If 'sslkey' is not specified 'sslcert' is assumed to
#			reference a combined file containing both the
#			certificate and the key.
#
#	sslversion=1|2|3|4
#			The SSL version to use when connecting to this peer
#				1 = automatic (default)
#				2 = SSL v2 only
#				3 = SSL v3 only
#				4 = TLS v1 only
#
#	sslcipher=...	The list of valid SSL ciphers to use when connecting
#			to this peer.
#
#	ssloptions=... 	Specify various SSL engine options:
#				NO_SSLv2  Disallow the use of SSLv2
#				NO_SSLv3  Disallow the use of SSLv3
#				NO_TLSv1  Disallow the use of TLSv1
#			See src/ssl_support.c or the OpenSSL documentation for
#			a more complete list.
#
#	sslcafile=... 	A file containing additional CA certificates to use
#			when verifying the peer certificate.
#
#	sslcapath=...	A directory containing additional CA certificates to
#			use when verifying the peer certificate.
#
#	sslcrlfile=... 	A certificate revocation list file to use when
#			verifying the peer certificate.
#
#	sslflags=...	Specify various flags modifying the SSL implementation:
#
#			DONT_VERIFY_PEER
#				Accept certificates even if they fail to
#				verify.
#			NO_DEFAULT_CA
#				Don't use the default CA list built in
#				to OpenSSL.
#			DONT_VERIFY_DOMAIN
#				Don't verify the peer certificate
#				matches the server name
#
#	ssldomain= 	The peer name as advertised in it's certificate.
#			Used for verifying the correctness of the received peer
#			certificate. If not specified the peer hostname will be
#			used.
#
#	front-end-https
#			Enable the "Front-End-Https: On" header needed when
#			using Squid as a SSL frontend in front of Microsoft OWA.
#			See MS KB document Q307347 for details on this header.
#			If set to auto the header will only be added if the
#			request is forwarded as a https:// URL.
#
#
#	==== GENERAL OPTIONS ====
#
#	connect-timeout=N
#			A peer-specific connect timeout.
#			Also see the peer_connect_timeout directive.
#
#	connect-fail-limit=N
#			How many times connecting to a peer must fail before
#			it is marked as down. Default is 10.
#
#	allow-miss	Disable Squid's use of only-if-cached when forwarding
#			requests to siblings. This is primarily useful when
#			icp_hit_stale is used by the sibling. To extensive use
#			of this option may result in forwarding loops, and you
#			should avoid having two-way peerings with this option.
#			For example to deny peer usage on requests from peer
#			by denying cache_peer_access if the source is a peer.
#
#	max-conn=N	Limit the amount of connections Squid may open to this
#			peer. see also
#
#	name=xxx	Unique name for the peer.
#			Required if you have multiple peers on the same host
#			but different ports.
#			This name can be used in cache_peer_access and similar
#			directives to dentify the peer.
#			Can be used by outgoing access controls through the
#			peername ACL type.
#
#	no-tproxy	Do not use the client-spoof TPROXY support when forwarding
#			requests to this peer. Use normal address selection instead.
#
#	proxy-only	objects fetched from the peer will not be stored locally.
#
#Default:
# none

#
#	For example, specifying

#	possible.  You can treat some domains differently than the the
#	default neighbor type specified on the 'cache_peer' line.
#	Normally it should only be necessary to list domains which
#	should be treated differently because the default neighbor type
#	applies for hostnames which do not match domains listed here.
#
#EXAMPLE:
#	cache_peer cache.foo.org parent 3128 3130
#	neighbor_type_domain cache.foo.org sibling .com .net
#	neighbor_type_domain cache.foo.org sibling .au .de
#Default:
# none

#  TAG: dead_peer_timeout	(seconds)
#	This controls how long Squid waits to declare a peer cache
#	as "dead."  If there are no ICP replies received in this
#	amount of time, Squid will declare the peer dead and not
#	expect to receive any further ICP replies.  However, it
#	continues to send ICP queries, and will mark the peer as
#	alive upon receipt of the first subsequent ICP reply.
#
#	This timeout also affects when Squid expects to receive ICP
#	replies from peers.  If more than 'dead_peer' seconds have
#	passed since the last ICP reply was received, Squid will not
#	expect to receive an ICP reply on the next query.  Thus, if
#	your time between requests is greater than this timeout, you
#	will see a lot of requests sent DIRECT to origin servers
#	instead of to your parents.
#Default:
# dead_peer_timeout 10 seconds
dead_peer_timeout %%dead_peer_timeout seconds

#  TAG: forward_max_tries
#	Controls how many different forward paths Squid will try
#	before giving up. See also forward_timeout.
#Default:
# forward_max_tries 10
forward_max_tries %%forward_max_tries


# MEMORY CACHE OPTIONS
# -----------------------------------------------------------------------------

#  TAG: cache_mem	(bytes)
#	NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS SIZE.
#	IT ONLY PLACES A LIMIT ON HOW MUCH ADDITIONAL MEMORY SQUID WILL
#	USE AS A MEMORY CACHE OF OBJECTS. SQUID USES MEMORY FOR OTHER
#	THINGS AS WELL. SEE THE SQUID FAQ SECTION 8 FOR DETAILS.
#
#	'cache_mem' specifies the ideal amount of memory to be used
#	for:
#		* In-Transit objects
#		* Hot Objects
#		* Negative-Cached objects
#
#	Data for these objects are stored in 4 KB blocks.  This
#	parameter specifies the ideal upper limit on the total size of
#	4 KB blocks allocated.  In-Transit objects take the highest
#	priority.
#
#	In-transit objects have priority over the others.  When
#	additional space is needed for incoming data, negative-cached
#	and hot objects will be released.  In other words, the
#	negative-cached and hot objects will fill up any unused space
#	not needed for in-transit objects.
#
#	If circumstances require, this limit will be exceeded.
#	Specifically, if your incoming request rate requires more than
#	'cache_mem' of memory to hold in-transit objects, Squid will
#	exceed this limit to satisfy the new requests.  When the load
#	decreases, blocks will be freed until the high-water mark is
#	reached.  Thereafter, blocks will be used to store hot
#	objects.
#Default:
# cache_mem 256 MB
cache_mem %%cache_mem MB

#  TAG: maximum_object_size_in_memory	(bytes)
#	Objects greater than this size will not be attempted to kept in
#	the memory cache. This should be set high enough to keep objects
#	accessed frequently in memory to improve performance whilst low
#	enough to keep larger objects from hoarding cache_mem.
#Default:
# maximum_object_size_in_memory 512 KB
maximum_object_size_in_memory %%maximum_object_size_in_memory KB

#  TAG: memory_replacement_policy
#	The memory replacement policy parameter determines which
#	objects are purged from memory when memory space is needed.
#
#	See cache_replacement_policy for details.
#Default:
# memory_replacement_policy lru
memory_replacement_policy %%memory_replacement_policy


# DISK CACHE OPTIONS
# -----------------------------------------------------------------------------

#  TAG: cache_replacement_policy
#	The cache replacement policy parameter determines which
#	objects are evicted (replaced) when disk space is needed.
#
#	    lru       : Squid's original list based LRU policy
#	    heap GDSF : Greedy-Dual Size Frequency
#	    heap LFUDA: Least Frequently Used with Dynamic Aging
#	    heap LRU  : LRU policy implemented using a heap
#
#	Applies to any cache_dir lines listed below this.
#
#	The LRU policies keeps recently referenced objects.
#
#	The heap GDSF policy optimizes object hit rate by keeping smaller
#	popular objects in cache so it has a better chance of getting a
#	hit.  It achieves a lower byte hit rate than LFUDA though since
#	it evicts larger (possibly popular) objects.
#
#	The heap LFUDA policy keeps popular objects in cache regardless of
#	their size and thus optimizes byte hit rate at the expense of
#	hit rate since one large, popular object will prevent many
#	smaller, slightly less popular objects from being cached.
#
#	Both policies utilize a dynamic aging mechanism that prevents
#	cache pollution that can otherwise occur with frequency-based
#	replacement policies.
#
#	NOTE: if using the LFUDA replacement policy you should increase
#	the value of maximum_object_size above its default of 4096 KB to
#	to maximize the potential byte hit rate improvement of LFUDA.
#
#	For more information about the GDSF and LFUDA cache replacement
#	policies see http://www.hpl.hp.com/techreports/1999/HPL-1999-69.html
#	and http://fog.hpl.external.hp.com/techreports/98/HPL-98-173.html.
#Default:
# cache_replacement_policy lru
cache_replacement_policy %%cache_replacement_policy


#  TAG: store_dir_select_algorithm
#	Set this to 'round-robin' as an alternative.
#Default:
# store_dir_select_algorithm least-load

#  TAG: max_open_disk_fds
#	To avoid having disk as the I/O bottleneck Squid can optionally
#	bypass the on-disk cache if more than this amount of disk file
#	descriptors are open.
#
#	A value of 0 indicates no limit.
#Default:
# max_open_disk_fds 0


#  TAG: cache_swap_low	(percent, 0-100)
#  TAG: cache_swap_high	(percent, 0-100)
#
#	The low- and high-water marks for cache object replacement.
#	Replacement begins when the swap (disk) usage is above the
#	low-water mark and attempts to maintain utilization near the
#	low-water mark.  As swap utilization gets close to high-water
#	mark object eviction becomes more aggressive.  If utilization is
#	close to the low-water mark less replacement is done each time.
#
#	Defaults are 90% and 95%. If you have a large cache, 5% could be
#	hundreds of MB. If this is the case you may wish to set these
#	numbers closer together.
#Default:
# cache_swap_low 90
# cache_swap_high 95
cache_swap_low %%cache_swap_low
cache_swap_high %%cache_swap_high

#  TAG: minimum_object_size	(bytes)
#   Objects smaller than this size will NOT be saved on disk.  The
#   value is specified in bytes, and the default is 0 KB, which
#   means all responses can be stored.
#Default:
# minimum_object_size 0 MB
minimum_object_size %%minimum_object_size KB

#  TAG: maximum_object_size	(bytes)
#   Set the default value for max-size parameter on any cache_dir.
#   The value is specified in bytes, and the default is 4 MB.
#
#   If you wish to get a high BYTES hit ratio, you should probably
#   increase this (one 32 MB object hit counts for 3200 10KB
#   hits).
#
#   If you wish to increase hit ratio more than you want to
#   save bandwidth you should leave this low.
#
#   NOTE: if using the LFUDA replacement policy you should increase
#   this value to maximize the byte hit rate improvement of LFUDA!
#   See cache_replacement_policy for a discussion of this policy.
#Default:
# maximum_object_size 4 MB (=4096 KB)
maximum_object_size %%maximum_object_size KB


# LOGFILE OPTIONS
# -----------------------------------------------------------------------------

#  TAG: logformat
#	Usage:
#
#	logformat <name> <format specification>
#
#	Defines an access log format.
#
#	The <format specification> is a string with embedded % format codes
#
#	% format codes all follow the same basic structure where all but
#	the formatcode is optional. Output strings are automatically escaped
#	as required according to their context and the output format
#	modifiers are usually not needed, but can be specified if an explicit
#	output format is desired.
#
#		% ["|[|'|#] [-] [[0]width] [{argument}] formatcode
#
#		"	output in quoted string format
#		[	output in squid text log format as used by log_mime_hdrs
#		#	output in URL quoted format
#		'	output as-is
#
#		-	left aligned
#		width	field width. If starting with 0 the
#			output is zero padded
#		{arg}	argument such as header name etc
#
#	Format codes:
#
#		%	a literal % character

#				default %d/%b/%Y:%H:%M:%S %z
#		tr	Response time (milliseconds)
#		dt	Total time spent making DNS lookups (milliseconds)
#
#	HTTP cache related format codes:
#
#		[http::]>h	Original request header. Optional header name argument
#				on the format header[:[separator]element]
#		[http::]>ha	The HTTP request headers after adaptation and redirection.
#				Optional header name argument as for >h
#		[http::]<h	Reply header. Optional header name argument
#				as for >h
#		[http::]un	User name
#		[http::]ul	User name from authentication
#		[http::]ui	User name from ident
#		[http::]us	User name from SSL
#		[http::]ue	User name from external acl helper
#		[http::]>Hs	HTTP status code sent to the client
#		[http::]<Hs	HTTP status code received from the next hop
#		[http::]Ss	Squid request status (TCP_MISS etc)
#		[http::]Sh	Squid hierarchy status (DEFAULT_PARENT etc)
#		[http::]mt	MIME content type
#		[http::]rm	Request method (GET/POST etc)
#		[http::]ru	Request URL
#		[http::]rp	Request URL-Path excluding hostname
#		[http::]rv	Request protocol version
#		[http::]et	Tag returned by external acl
#		[http::]ea	Log string returned by external acl
#		[http::]<st	Sent reply size including HTTP headers
#		[http::]>st	Received request size including HTTP headers. In the
#				case of chunked requests the chunked encoding metadata
#				are not included
#		[http::]>sh	Received HTTP request headers size
#		[http::]<sh	Sent HTTP reply headers size
#		[http::]st	Request+Reply size including HTTP headers
#		[http::]<sH	Reply high offset sent
#		[http::]<sS	Upstream object size
#		[http::]<pt	Peer response time in milliseconds. The timer starts
#				when the last request byte is sent to the next hop
#				and stops when the last response byte is received.
#		[http::]<tt	Total server-side time in milliseconds. The timer
#				starts with the first connect request (or write I/O)
#				sent to the first selected peer. The timer stops
#				with the last I/O with the last peer.
#
#	If ICAP is enabled, the following two codes become available (as
#	well as ICAP log codes documented with the icap_log option):
#
#		icap::tt        Total ICAP processing time for the HTTP
#				transaction. The timer ticks when ICAP
#				ACLs are checked and when ICAP
#				transaction is in progress.
#
#		icap::<last_h	The header of the last ICAP response
#				related to the HTTP transaction. Like
#				<h, accepts an optional header name
#				argument.  Will not change semantics
#				when multiple ICAP transactions per HTTP
#				transaction are supported.
#
#	If adaptation is enabled the following two codes become available:
#
#		adapt::sum_trs Summed adaptation transaction response
#				times recorded as a comma-separated list in
#				the order of transaction start time. Each time
#				value is recorded as an integer number,
#				representing response time of one or more
#				adaptation (ICAP or eCAP) transaction in
#				milliseconds.  When a failed transaction is
#				being retried or repeated, its time is not
#				logged individually but added to the
#				replacement (next) transaction. See also:
#				adapt::all_trs.
#
#		adapt::all_trs All adaptation transaction response times.
#				Same as adaptation_strs but response times of
#				individual transactions are never added
#				together. Instead, all transaction response
#				times are recorded individually.
#
#	You can prefix adapt::*_trs format codes with adaptation
#	service name in curly braces to record response time(s) specific
#	to that service. For example: %{my_service}adapt::sum_trs
#
#	The default formats available (which do not need re-defining) are:
#
#logformat squid %ts.%03tu %6tr %>a %Ss/%03>Hs %<st %rm %ru %un %Sh/%<A %mt
#logformat squidmime %ts.%03tu %6tr %>a %Ss/%03>Hs %<st %rm %ru %un %Sh/%<A %mt [%>h] [%<h]
#logformat common %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %>Hs %<st %Ss:%Sh
#logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %>Hs %<st "%{Referer}>h" "%{User-Agent}>h" %Ss:%Sh
#Default:
# none

#  TAG: icap_log
#	ICAP log files record ICAP transaction summaries, one line per
#	transaction.
#
#	The icap_log option format is:
#	icap_log <filepath> [<logformat name> [acl acl ...]]
#	icap_log none [acl acl ...]]
#
#	Please see access_log option documentation for details. The two
#	kinds of logs share the overall configuration approach and many
#	features.
#
#	ICAP processing of a single HTTP message or transaction may
#	require multiple ICAP transactions.  In such cases, multiple
#	ICAP transaction log lines will correspond to a single access
#	log line.
#
#	ICAP log uses logformat codes that make sense for an ICAP
#	transaction. Header-related codes are applied to the HTTP header
#	embedded in an ICAP server response, with the following caveats:
#	For REQMOD, there is no HTTP response header unless the ICAP
#	server performed request satisfaction. For RESPMOD, the HTTP
#	request header is the header sent to the ICAP server. For
#	OPTIONS, there are no HTTP headers.
#
#	The following format codes are also available for ICAP logs:
#
#		icap::<A	ICAP server IP address. Similar to <A.
#
#		icap::<service_name	ICAP service name from the icap_service
#				option in Squid configuration file.
#
#		icap::ru	ICAP Request-URI. Similar to ru.
#
#		icap::rm	ICAP request method (REQMOD, RESPMOD, or
#				OPTIONS). Similar to existing rm.
#
#		icap::>st	Bytes sent to the ICAP server (TCP payload
#				only; i.e., what Squid writes to the socket).
#
#		icap::<st	Bytes received from the ICAP server (TCP
#				payload only; i.e., what Squid reads from
#				the socket).
#
#		icap::tr 	Transaction response time (in
#				milliseconds).  The timer starts when
#				the ICAP transaction is created and
#				stops when the transaction is completed.
#				Similar to tr.
#
#		icap::tio	Transaction I/O time (in milliseconds). The
#				timer starts when the first ICAP request
#				byte is scheduled for sending. The timers
#				stops when the last byte of the ICAP response
#				is received.
#
#		icap::to 	Transaction outcome: ICAP_ERR* for all
#				transaction errors, ICAP_OPT for OPTION
#				transactions, ICAP_ECHO for 204
#				responses, ICAP_MOD for message
#				modification, and ICAP_SAT for request
#				satisfaction. Similar to Ss.
#
#		icap::Hs	ICAP response status code. Similar to Hs.
#
#		icap::>h	ICAP request header(s). Similar to >h.
#
#		icap::<h	ICAP response header(s). Similar to <h.
#
#	The default ICAP log format, which can be used without an explicit
#	definition, is called icap_squid:
#
#logformat icap_squid %ts.%03tu %6icap::tr %>a %icap::to/%03icap::Hs %icap::<size %icap::rm %icap::ru% %un -/%icap::<A -
#
#	See also: logformat, log_icap, and %icap::<last_h
#Default:
# none

#  TAG: cache_store_log
#	Logs the activities of the storage manager.  Shows which
#	objects are ejected from the cache, and which objects are
#	saved and for how long.  To disable, enter "none" or remove the line.
#	There are not really utilities to analyze this data, so you can safely
#	disable it.
#
#	Example:
#		cache_store_log /var/log/squid/store.log
#Default:
# none
##EOLE
cache_store_log  none

#  TAG: cache_swap_state
#	Location for the cache "swap.state" file. This index file holds
#	the metadata of objects saved on disk.  It is used to rebuild
#	the cache during startup.  Normally this file resides in each
#	'cache_dir' directory, but you may specify an alternate
#	pathname here.  Note you must give a full filename, not just
#	a directory. Since this is the index for the whole object
#	list you CANNOT periodically rotate it!
#
#	If %s can be used in the file name it will be replaced with a
#	a representation of the cache_dir name where each / is replaced
#	with '.'. This is needed to allow adding/removing cache_dir
#	lines when cache_swap_log is being used.
#
#	If have more than one 'cache_dir', and %s is not used in the name
#	these swap logs will have names such as:
#
#		cache_swap_log.00
#		cache_swap_log.01
#		cache_swap_log.02
#
#	The numbered extension (which is added automatically)
#	corresponds to the order of the 'cache_dir' lines in this
#	configuration file.  If you change the order of the 'cache_dir'
#	lines in this file, these index files will NOT correspond to
#	the correct 'cache_dir' entry (unless you manually rename
#	them).  We recommend you do NOT use this option.  It is
#	better to keep these index files in each 'cache_dir' directory.
#Default:
# none

#  TAG: logfile_rotate
#	Specifies the number of logfile rotations to make when you
#	type 'squid -k rotate'. The default is 10, which will rotate
#	with extensions 0 through 9. Setting logfile_rotate to 0 will
#	disable the file name rotation, but the logfiles are still closed
#	and re-opened. This will enable you to rename the logfiles
#	yourself just before sending the rotate signal.
#
#	Note, the 'squid -k rotate' command normally sends a USR1
#	signal to the running squid process.  In certain situations
#	(e.g. on Linux with Async I/O), USR1 is used for other
#	purposes, so -k rotate uses another signal.  It is best to get
#	in the habit of using 'squid -k rotate' instead of 'kill -USR1
#	<pid>'.
#
#	Note, from Squid-3.1 this option has no effect on the cache.log,
#	that log can be rotated separately by using debug_options
#
# 	Note2, for Debian/Linux the default of logfile_rotate is
# 	zero, since it includes external logfile-rotation methods.
#Default:
# logfile_rotate 0

#  TAG: mime_table
#	Pathname to Squid's MIME table. You shouldn't need to change
#	this, but the default file contains examples and formatting
#	information if you do.
#Default:
# mime_table /usr/share/squid/mime.conf

#  TAG: log_mime_hdrs	on|off
#	The Cache can record both the request and the response MIME
#	headers for each HTTP transaction.  The headers are encoded
#	safely and will appear as two bracketed fields at the end of
#	the access log (for either the native or httpd-emulated log
#	formats).  To enable this logging set log_mime_hdrs to 'on'.
#Default:
# log_mime_hdrs off
log_mime_hdrs %%log_mime_hdrs

#  TAG: client_netmask
#	A netmask for client addresses in logfiles and cachemgr output.
#	Change this to protect the privacy of your cache clients.
#	A netmask of 255.255.255.0 will log all IP's in that range with
#	the last digit set to '0'.
#Default:
# client_netmask no_addr
client_netmask %%client_netmask

#  TAG: forward_log
# Note: This option is only available if Squid is rebuilt with the
#       -DWIP_FWD_LOG define
#
#	Logs the server-side requests.
#
#	This is currently work in progress.
#Default:
# none

#  TAG: strip_query_terms
#	By default, Squid strips query terms from requested URLs before
#	logging.  This protects your user's privacy.
#Default:
# strip_query_terms on
strip_query_terms %%strip_query_terms

#  TAG: buffered_logs	on|off
#	cache.log log file is written with stdio functions, and as such
#	it can be buffered or unbuffered. By default it will be unbuffered.
#	Buffering it can speed up the writing slightly (though you are
#	unlikely to need to worry unless you run with tons of debugging
#	enabled in which case performance will suffer badly anyway..).
#Default:
# buffered_logs off

#  TAG: netdb_filename
# Note: This option is only available if Squid is rebuilt with the
#       --enable-icmp option
#
#	A filename where Squid stores it's netdb state between restarts.
#	To disable, enter "none".
#Default:
# netdb_filename /var/log/squid/netdb.state

# OPTIONS FOR TROUBLESHOOTING
# -----------------------------------------------------------------------------

#  TAG: cache_log
#	Cache logging file. This is where general information about
#	your cache's behavior goes. You can increase the amount of data
#	logged to this file and how often its rotated with "debug_options"
#Default:
# cache_log /var/log/squid/cache.log
#cache_log /var/log/squid/cache.log


#  TAG: debug_options
#	Logging options are set as section,level where each source file
#	is assigned a unique section.  Lower levels result in less
#	output,  Full debugging (level 9) can result in a very large
#	log file, so be careful.
#
#	The magic word "ALL" sets debugging levels for all sections.
#	We recommend normally running with "ALL,1".
#
#	The rotate=N option can be used to keep more or less of these logs
#	than would otherwise be kept by logfile_rotate.
#	For most uses a single log should be enough to monitor current
#	events affecting Squid.
#Default:
# debug_options ALL,1

#  TAG: coredump_dir
#	By default Squid leaves core files in the directory from where
#	it was started. If you set 'coredump_dir' to a directory
#	that exists, Squid will chdir() to that directory at startup
#	and coredump files will be left there.
#
#Default:
# coredump_dir none
#

# Leave coredumps in the first cache dir
coredump_dir /var/spool/squid

# OPTIONS FOR FTP GATEWAYING
# -----------------------------------------------------------------------------

#  TAG: ftp_user
#	If you want the anonymous login password to be more informative
#	(and enable the use of picky ftp servers), set this to something
#	reasonable for your domain, like wwwuser@somewhere.net
#
#	The reason why this is domainless by default is the
#	request can be made on the behalf of a user in any domain,
#	depending on how the cache is used.
#	Some ftp server also validate the email address is valid
#	(for example perl.com).
#Default:
# ftp_user Squid@
## EOLE
ftp_user %%ftp_user@%%nom_academie.%%suffixe_domaine_academique

#  TAG: ftp_passive
#	If your firewall does not allow Squid to use passive
#	connections, turn off this option.
#
#	Use of ftp_epsv_all option requires this to be ON.
#Default:
# ftp_passive on
ftp_passive %%ftp_passive

#  TAG: ftp_epsv_all
#	FTP Protocol extensions permit the use of a special "EPSV ALL" command.
#
#	NATs may be able to put the connection on a "fast path" through the
#	translator, as the EPRT command will never be used and therefore,
#	translation of the data portion of the segments will never be needed.
#
#	When a client only expects to do two-way FTP transfers this may be
#	useful.
#	If squid finds that it must do a three-way FTP transfer after issuing
#	an EPSV ALL command, the FTP session will fail.
#
#	If you have any doubts about this option do not use it.
#	Squid will nicely attempt all other connection methods.
#
#	Requires ftp_passive to be ON (default) for any effect.
#Default:
# ftp_epsv_all off

#  TAG: ftp_epsv
#	FTP Protocol extensions permit the use of a special "EPSV" command.
#
#	NATs may be able to put the connection on a "fast path" through the
#	translator using EPSV, as the EPRT command will never be used
#	and therefore, translation of the data portion of the segments
#	will never be needed.
#
#	Turning this OFF will prevent EPSV being attempted.
#	WARNING: Doing so will convert Squid back to the old behavior with all
#	the related problems with external NAT devices/layers.
#
#	Requires ftp_passive to be ON (default) for any effect.
#Default:
# ftp_epsv on

#  TAG: ftp_sanitycheck
#	For security and data integrity reasons Squid by default performs
#	sanity checks of the addresses of FTP data connections ensure the
#	data connection is to the requested server. If you need to allow
#	FTP connections to servers using another IP address for the data
#	connection turn this off.
#Default:
# ftp_sanitycheck on
ftp_sanitycheck %%ftp_sanitycheck

#  TAG: ftp_telnet_protocol
#	The FTP protocol is officially defined to use the telnet protocol
#	as transport channel for the control connection. However, many
#	implementations are broken and does not respect this aspect of
#	the FTP protocol.
#
#	If you have trouble accessing files with ASCII code 255 in the
#	path or similar problems involving this ASCII code you can
#	try setting this directive to off. If that helps, report to the
#	operator of the FTP server in question that their FTP server
#	is broken and does not follow the FTP standard.
#Default:
# ftp_telnet_protocol on
ftp_telnet_protocol %%ftp_telnet_protocol

# OPTIONS FOR EXTERNAL SUPPORT PROGRAMS
# -----------------------------------------------------------------------------

#  TAG: diskd_program
#	Specify the location of the diskd executable.
#	Note this is only useful if you have compiled in
#	diskd as one of the store io modules.
#Default:
# diskd_program /usr/lib/squid/diskd

#  TAG: unlinkd_program
#	Specify the location of the executable for file deletion process.
#Default:
# unlinkd_program /usr/lib/squid/unlinkd

#  TAG: pinger_program
# Note: This option is only available if Squid is rebuilt with the
#       --enable-icmp option
#
#	Specify the location of the executable for the pinger process.
#Default:
# pinger_program /usr/lib/squid/pinger

#  TAG: pinger_enable
# Note: This option is only available if Squid is rebuilt with the
#       --enable-icmp option
#
#	Control whether the pinger is active at run-time.
#	Enables turning ICMP pinger on and off with a simple
#	squid -k reconfigure.
#Default:
# pinger_enable off

# OPTIONS FOR URL REWRITING
# -----------------------------------------------------------------------------

#  TAG: url_rewrite_program
#	Specify the location of the executable for the URL rewriter.
#	Since they can perform almost any function there isn't one included.
#
#	For each requested URL rewriter will receive on line with the format
#
#	URL <SP> client_ip "/" fqdn <SP> user <SP> method [<SP> kvpairs]<NL>
#
#	In the future, the rewriter interface will be extended with
#	key=value pairs ("kvpairs" shown above).  Rewriter programs
#	should be prepared to receive and possibly ignore additional
#	whitespace-separated tokens on each input line.
#
#	And the rewriter may return a rewritten URL. The other components of
#	the request line does not need to be returned (ignored if they are).
#
#	The rewriter can also indicate that a client-side redirect should
#	be performed to the new URL. This is done by prefixing the returned
#	URL with "301:" (moved permanently) or 302: (moved temporarily).
#
#	By default, a URL rewriter is not used.
#Default:
# none

#  TAG: url_rewrite_children
#	The number of redirector processes to spawn. If you start
#	too few Squid will have to wait for them to process a backlog of
#	URLs, slowing it down. If you start too many they will use RAM
#	and other system resources.
#Default:
# url_rewrite_children 5

#  TAG: url_rewrite_host_header
#	By default Squid rewrites any Host: header in redirected
#	requests.  If you are running an accelerator this may
#	not be a wanted effect of a redirector.
#
#	WARNING: Entries are cached on the result of the URL rewriting
#	process, so be careful if you have domain-virtual hosts.
#Default:
# url_rewrite_host_header on

#  TAG: url_rewrite_access
#	If defined, this access list specifies which requests are
#	sent to the redirector processes.  By default all requests
#	are sent.
#
#	This clause supports both fast and slow acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#Default:
# none

#  TAG: url_rewrite_bypass
#	When this is 'on', a request will not go through the
#	redirector if all redirectors are busy.  If this is 'off'
#	and the redirector queue grows too large, Squid will exit
#	with a FATAL error and ask you to increase the number of
#	redirectors.  You should only enable this if the redirectors
#	are not critical to your caching system.  If you use
#	redirectors for access control, and you enable this option,
#	users may have access to pages they should not
#	be allowed to request.
#Default:
# url_rewrite_bypass off

# OPTIONS FOR TUNING THE CACHE
# -----------------------------------------------------------------------------

#  TAG: cache
#	A list of ACL elements which, if matched and denied, cause the request to
#	not be satisfied from the cache and the reply to not be cached.
#	In other words, use this to force certain objects to never be cached.
#
#	You must use the words 'allow' or 'deny' to indicate whether items
#	matching the ACL should be allowed or denied into the cache.
#
#	Default is to allow all to be cached.
#
#	This clause supports both fast and slow acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#Default:
# none

#  TAG: refresh_pattern
#	usage: refresh_pattern [-i] regex min percent max [options]
#
#	By default, regular expressions are CASE-SENSITIVE.  To make
#	them case-insensitive, use the -i option.
#
#	'Min' is the time (in minutes) an object without an explicit
#	expiry time should be considered fresh. The recommended
#	value is 0, any higher values may cause dynamic applications
#	to be erroneously cached unless the application designer
#	has taken the appropriate actions.
#
#	'Percent' is a percentage of the objects age (time since last
#	modification age) an object without explicit expiry time
#	will be considered fresh.
#
#	'Max' is an upper limit on how long objects without an explicit
#	expiry time will be considered fresh.
#
#	options: override-expire

#		 ignore-reload
#		 ignore-no-cache
#		 ignore-no-store
#		 ignore-must-revalidate
#		 ignore-private
#		 ignore-auth
#		 refresh-ims
#
#		override-expire enforces min age even if the server
#		sent an explicit expiry time (e.g., with the
#		Expires: header or Cache-Control: max-age). Doing this
#		VIOLATES the HTTP standard.  Enabling this feature
#		could make you liable for problems which it causes.
#
#		Note: override-expire does not enforce staleness - it only extends
#		freshness / min. If the server returns a Expires time which
#		is longer than your max time, Squid will still consider
#		the object fresh for that period of time.
#
#		override-lastmod enforces min age even on objects
#		that were modified recently.
#
#		reload-into-ims changes client no-cache or ``reload''
#		to If-Modified-Since requests. Doing this VIOLATES the
#		HTTP standard. Enabling this feature could make you
#		liable for problems which it causes.
#
#		ignore-reload ignores a client no-cache or ``reload''
#		header. Doing this VIOLATES the HTTP standard. Enabling
#		this feature could make you liable for problems which
#		it causes.
#
#		ignore-no-cache ignores any ``Pragma: no-cache'' and
#		``Cache-control: no-cache'' headers received from a server.
#		The HTTP RFC never allows the use of this (Pragma) header
#		from a server, only a client, though plenty of servers
#		send it anyway.
#
#		ignore-no-store ignores any ``Cache-control: no-store''
#		headers received from a server. Doing this VIOLATES
#		the HTTP standard. Enabling this feature could make you
#		liable for problems which it causes.
#
#		ignore-must-revalidate ignores any ``Cache-Control: must-revalidate``
#		headers received from a server. Doing this VIOLATES
#		the HTTP standard. Enabling this feature could make you
#		liable for problems which it causes.
#
#		ignore-private ignores any ``Cache-control: private''
#		headers received from a server. Doing this VIOLATES
#		the HTTP standard. Enabling this feature could make you
#		liable for problems which it causes.
#
#		ignore-auth caches responses to requests with authorization,
#		as if the originserver had sent ``Cache-control: public''
#		in the response header. Doing this VIOLATES the HTTP standard.
#		Enabling this feature could make you liable for problems which
#		it causes.
#
#		refresh-ims causes squid to contact the origin server
#		when a client issues an If-Modified-Since request. This
#		ensures that the client will receive an updated version
#		if one is available.
#
#	Basically a cached object is:
#
#		FRESH if expires < now, else STALE
#		STALE if age > max
#		FRESH if lm-factor < percent, else STALE
#		FRESH if age < min
#		else STALE
#
#	The refresh_pattern lines are checked in the order listed here.

#  TAG: quick_abort_min	(KB)
#  TAG: quick_abort_max	(KB)
#  TAG: quick_abort_pct	(percent)
#	The cache by default continues downloading aborted requests
#	which are almost completed (less than 16 KB remaining). This
#	may be undesirable on slow (e.g. SLIP) links and/or very busy
#	caches.  Impatient users may tie up file descriptors and
#	bandwidth by repeatedly requesting and immediately aborting
#	downloads.
#
#	When the user aborts a request, Squid will check the
#	quick_abort values to the amount of data transfered until
#	then.
#
#	If the transfer has less than 'quick_abort_min' KB remaining,
#	it will finish the retrieval.
#
#	If the transfer has more than 'quick_abort_max' KB remaining,
#	it will abort the retrieval.
#
#	If more than 'quick_abort_pct' of the transfer has completed,
#	it will finish the retrieval.
#
#	If you do not want any retrieval to continue after the client
#	has aborted, set both 'quick_abort_min' and 'quick_abort_max'
#	to '0 KB'.
#
#	If you want retrievals to always continue if they are being
#	cached set 'quick_abort_min' to '-1 KB'.
#Default:
# quick_abort_min 16 KB
# quick_abort_max 16 KB
# quick_abort_pct 95
quick_abort_min %%quick_abort_min KB
quick_abort_max %%quick_abort_max KB

#  TAG: read_ahead_gap	buffer-size
#	The amount of data the cache will buffer ahead of what has been
#	sent to the client when retrieving an object from another server.
#Default:
# read_ahead_gap 16 KB
read_ahead_gap %%read_ahead_gap KB

#  TAG: negative_ttl	time-units
#	Set the Default Time-to-Live (TTL) for failed requests.
#	Certain types of failures (such as "connection refused" and
#	"404 Not Found") are able to be negatively-cached for a short time.
#	Modern web servers should provide Expires: header, however if they
#	do not this can provide a minimum TTL.
#	The default is not to cache errors with unknown expiry details.
#
#	Note that this is different from negative caching of DNS lookups.
#
#	WARNING: Doing this VIOLATES the HTTP standard.  Enabling
#	this feature could make you liable for problems which it
#	causes.
#Default:
# negative_ttl 0 seconds
negative_ttl %%negative_ttl minutes

#  TAG: positive_dns_ttl	time-units
#	Upper limit on how long Squid will cache positive DNS responses.
#	Default is 6 hours (360 minutes). This directive must be set
#	larger than negative_dns_ttl.
#Default:
# positive_dns_ttl 6 hours
positive_dns_ttl %%positive_dns_ttl hours

#  TAG: negative_dns_ttl	time-units
#	Time-to-Live (TTL) for negative caching of failed DNS lookups.
#	This also sets the lower cache limit on positive lookups.
#	Minimum value is 1 second, and it is not recommendable to go
#	much below 10 seconds.
#Default:
# negative_dns_ttl 1 minutes
negative_dns_ttl %%negative_dns_ttl minutes

#  TAG: range_offset_limit	(bytes)
#	Sets a upper limit on how far into the the file a Range request
#	may be to cause Squid to prefetch the whole file. If beyond this
#	limit Squid forwards the Range request as it is and the result
#	is NOT cached.
#
#	This is to stop a far ahead range request (lets say start at 17MB)
#	from making Squid fetch the whole object up to that point before
#	sending anything to the client.
#
#	A value of 0 causes Squid to never fetch more than the
#	client requested. (default)
#
#	A value of -1 causes Squid to always fetch the object from the
#	beginning so it may cache the result. (2.0 style)
#
#	NP: Using -1 here will override any quick_abort settings that may
#	    otherwise apply to the range request. The range request will
#	    be fully fetched from start to finish regardless of the client
#	    actions. This affects bandwidth usage.
#Default:
# range_offset_limit 0 KB
#range_offset_limit %%range_offset_limit KB #FIXME 2.5 : #10729

#  TAG: minimum_expiry_time	(seconds)
#	The minimum caching time according to (Expires - Date)
#	Headers Squid honors if the object can't be revalidated
#	defaults to 60 seconds. In reverse proxy environments it
#	might be desirable to honor shorter object lifetimes. It
#	is most likely better to make your server return a
#	meaningful Last-Modified header however. In ESI environments
#	where page fragments often have short lifetimes, this will
#	often be best set to 0.
#Default:
# minimum_expiry_time 60 seconds

#  TAG: store_avg_object_size	(kbytes)
#	Average object size, used to estimate number of objects your
#	cache can hold.  The default is 13 KB.
#Default:
# store_avg_object_size 13 KB

#  TAG: store_objects_per_bucket
#	Target number of objects per bucket in the store hash table.
#	Lowering this value increases the total number of buckets and
#	also the storage maintenance rate.  The default is 20.
#Default:
# store_objects_per_bucket 20

# HTTP OPTIONS

#  TAG: request_header_max_size	(KB)
#	This specifies the maximum size for HTTP headers in a request.
#	Request headers are usually relatively small (about 512 bytes).
#	Placing a limit on the request header size will catch certain
#	bugs (for example with persistent connections) and possibly

#  TAG: broken_posts
#	A list of ACL elements which, if matched, causes Squid to send
#	an extra CRLF pair after the body of a PUT/POST request.
#
#	Some HTTP servers has broken implementations of PUT/POST,
#	and rely on an extra CRLF pair sent by some WWW clients.
#
#	Quote from RFC2616 section 4.1 on this matter:
#
#	  Note: certain buggy HTTP/1.0 client implementations generate an
#	  extra CRLF's after a POST request. To restate what is explicitly
#	  forbidden by the BNF, an HTTP/1.1 client must not preface or follow
#	  a request with an extra CRLF.
#
#	This clause only supports fast acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#
#Example:
# acl buggy_server url_regex ^http://....
# broken_posts allow buggy_server
#Default:
# none

#  TAG: icap_uses_indirect_client	on|off
#   Controls whether the indirect client address
#   (see follow_x_forwarded_for) instead of the
#   direct client address is passed to an ICAP
#   server as "X-Client-IP".
#Default:
# icap_uses_indirect_client on

#  TAG: via	on|off
#	If set (default), Squid will include a Via header in requests and
#	replies as required by RFC2616.
#Default:
#via on

#  TAG: vary_ignore_expire	on|off
#	Many HTTP servers supporting Vary gives such objects
#	immediate expiry time with no cache-control header
#	when requested by a HTTP/1.0 client. This option
#	enables Squid to ignore such expiry times until
#	HTTP/1.1 is fully implemented.
#
#	WARNING: If turned on this may eventually cause some
#	varying objects not intended for caching to get cached.
#Default:
# vary_ignore_expire off

#  TAG: request_entities
#	Squid defaults to deny GET and HEAD requests with request entities,
#	as the meaning of such requests are undefined in the HTTP standard
#	even if not explicitly forbidden.
#
#	Set this directive to on if you have clients which insists
#	on sending request entities in GET or HEAD requests. But be warned
#	that there is server software (both proxies and web servers) which
#	can fail to properly process this kind of request which may make you
#	vulnerable to cache pollution attacks if enabled.
#Default:
# request_entities off

#  TAG: request_header_access
#	Usage: request_header_access header_name allow|deny [!]aclname ...
#
#	WARNING: Doing this VIOLATES the HTTP standard.  Enabling
#	this feature could make you liable for problems which it
#	causes.
#
#	This option replaces the old 'anonymize_headers' and the
#	older 'http_anonymizer' option with something that is much
#	more configurable. This new method creates a list of ACLs
#	for each header, allowing you very fine-tuned header
#	mangling.
#
#	This option only applies to request headers, i.e., from the
#	client to the server.
#
#	You can only specify known headers for the header name.
#	Other headers are reclassified as 'Other'. You can also
#	refer to all the headers with 'All'.
#
#	For example, to achieve the same behavior as the old

#
#	If set to "warn" then a warning will be emitted in cache.log

# TIMEOUTS
# -----------------------------------------------------------------------------

#Default:
# forward_timeout 4 minutes
forward_timeout %%forward_timeout seconds

#  TAG: connect_timeout	time-units
#	This parameter specifies how long to wait for the TCP connect to
#	the requested server or peer to complete before Squid should
#	attempt to find another path where to forward the request.
#Default:
# connect_timeout 1 minute
connect_timeout %%connect_timeout seconds

#  TAG: peer_connect_timeout	time-units
#	This parameter specifies how long to wait for a pending TCP
#	connection to a peer cache.  The default is 30 seconds.   You
#	may also set different timeout values for individual neighbors
#	with the 'connect-timeout' option on a 'cache_peer' line.
#Default:
# peer_connect_timeout 30 seconds
peer_connect_timeout %%peer_connect_timeout seconds

#  TAG: read_timeout	time-units
#	The read_timeout is applied on server-side connections.  After
#	each successful read(), the timeout will be extended by this
#	amount.  If no data is read again after this amount of time,
#	the request is aborted and logged with ERR_READ_TIMEOUT.  The
#	default is 15 minutes.
#Default:

#  TAG: client_lifetime	time-units
#	The maximum amount of time a client (browser) is allowed to
#	remain connected to the cache process.  This protects the Cache
#	from having a lot of sockets (and hence file descriptors) tied up
#	in a CLOSE_WAIT state from remote clients that go away without
#	properly shutting down (either because of a network failure or
#	because of a poor client implementation).  The default is one
#	day, 1440 minutes.
#
#	NOTE:  The default value is intended to be much larger than any
#	client would ever need to be connected to your cache.  You
#	should probably change client_lifetime only as a last resort.
#	If you seem to have many client connections tying up
#	filedescriptors, we recommend first tuning the read_timeout,

#Default:
# client_lifetime 1 day
#EOLE
#client_lifetime 120 minutes
client_lifetime %%client_lifetime minutes

#  TAG: half_closed_clients
#	Some clients may shutdown the sending side of their TCP

#	Squid can not tell the difference between a half-closed and a
#	fully-closed TCP connection.
#
#	By default, Squid will immediately close client connections when
#	read(2) returns "no more data to read."
#
#	Change this option to 'on' and Squid will keep open connections
#	until a read(2) or write(2) on the socket returns an error.
#	This may show some benefits for reverse proxies. But if not
#	it is recommended to leave OFF.
#Default:
# half_closed_clients off
half_closed_clients %%half_closed_clients

#  TAG: pconn_timeout
#	Timeout for idle persistent connections to servers and other
#	proxies.
#Default:
# pconn_timeout 1 minute
pconn_timeout %%pconn_timeout seconds

#  TAG: shutdown_lifetime	time-units
#	When SIGTERM or SIGHUP is received, the cache is put into
#	"shutdown pending" mode until all active sockets are closed.
#	This value is the lifetime to set for all open descriptors
#	during shutdown mode.  Any active clients after this many
#	seconds will receive a 'timeout' message.
#Default:
# shutdown_lifetime 30 seconds
shutdown_lifetime %%shutdown_lifetime seconds

# ADMINISTRATIVE PARAMETERS
# -----------------------------------------------------------------------------

#  TAG: cache_mgr
#	Email-address of local cache manager who will receive
#	mail if the cache dies.  The default is "webmaster."
#Default:
# cache_mgr webmaster

#  TAG: mail_from
#	From: email-address for mail sent when the cache dies.
#	The default is to use 'appname@unique_hostname'.
#	Default appname value is "squid", can be changed into
#	src/globals.h before building squid.
#Default:
# none

#  TAG: mail_program
#	Email program used to send mail if the cache dies.
#	The default is "mail". The specified program must comply
#	with the standard Unix mail syntax:
#	  mail-program recipient < mailfile
#
#	Optional command line options can be specified.
#Default:
# mail_program mail

#  TAG: cache_effective_user
#	If you start Squid as root, it will change its effective/real
#	UID/GID to the user specified below.  The default is to change
#	to UID of proxy.
#	see also; cache_effective_group
#Default:
cache_effective_user proxy

#  TAG: cache_effective_group
#	Squid sets the GID to the effective user's default group ID
#	(taken from the password file) and supplementary group list
#	from the groups membership.
#
#	If you want Squid to run with a specific GID regardless of
#	the group memberships of the effective user then set this
#	to the group (or GID) you want Squid to run as. When set
#	all other group privileges of the effective user are ignored
#	and only this GID is effective. If Squid is not started as
#	root the user starting Squid MUST be member of the specified
#	group.
#
#	This option is not recommended by the Squid Team.
#	Our preference is for administrators to configure a secure
#	user account for squid with UID/GID matching system policies.
#Default:
# none
##EOLE
cache_effective_group proxy

#  TAG: httpd_suppress_version_string	on|off
#	Suppress Squid version string info in HTTP headers and HTML error pages.
#Default:
# httpd_suppress_version_string off

#  TAG: visible_hostname
#	If you want to present a special hostname in error messages, etc,
#	define this.  Otherwise, the return value of gethostname()
#	will be used. If you have multiple caches in a cluster and
#	get errors about IP-forwarding you must set them to have individual
#	names with this setting.
#Default:
# visible_hostname localhost

#  TAG: unique_hostname
#	If you want to have multiple machines with the same
#	'visible_hostname' you must give each machine a different
#	'unique_hostname' so forwarding loops can be detected.
#Default:
# none

#  TAG: hostname_aliases
#	A list of other DNS names your cache has.
#Default:
# none

#  TAG: umask
#	Minimum umask which should be enforced while the proxy
#	is running, in addition to the umask set at startup.
#
#	For a traditional octal representation of umasks, start
#        your value with 0.
#Default:
# umask 027

# OPTIONS FOR THE CACHE REGISTRATION SERVICE
# -----------------------------------------------------------------------------
#
#	This section contains parameters for the (optional) cache
#	announcement service.  This service is provided to help
#	cache administrators locate one another in order to join or
#	create cache hierarchies.
#
#	An 'announcement' message is sent (via UDP) to the registration
#	service by Squid.  By default, the announcement message is NOT
#	SENT unless you enable it with 'announce_period' below.
#
#	The announcement message includes your hostname, plus the
#	following information from this configuration file:
#
#		http_port
#		icp_port
#		cache_mgr
#
#	All current information is processed regularly and made
#	available on the Web at http://www.ircache.net/Cache/Tracker/.

#  TAG: announce_period
#	This is how frequently to send cache announcements.  The
#	default is `0' which disables sending the announcement
#	messages.
#
#	To enable announcing your cache, just set an announce period.
#
#	Example:
#		announce_period 1 day
#Default:
# announce_period 0

#  TAG: announce_host
#  TAG: announce_file
#  TAG: announce_port
#	announce_host and announce_port set the hostname and port
#	number where the registration message will be sent.
#
#	Hostname will default to 'tracker.ircache.net' and port will
#	default default to 3131.  If the 'filename' argument is given,
#	the contents of that file will be included in the announce
#	message.
#Default:
# announce_host tracker.ircache.net
# announce_port 3131

# HTTPD-ACCELERATOR OPTIONS
# -----------------------------------------------------------------------------

#  TAG: httpd_accel_surrogate_id
#	Surrogates (http://www.esi.org/architecture_spec_1.0.html)
#	need an identification token to allow control targeting. Because
#	a farm of surrogates may all perform the same tasks, they may share
#	an identification token.
#Default:
# httpd_accel_surrogate_id unset-id

#  TAG: http_accel_surrogate_remote	on|off
#	Remote surrogates (such as those in a CDN) honour Surrogate-Control: no-store-remote.
#	Set this to on to have squid behave as a remote surrogate.
#Default:
# http_accel_surrogate_remote off

#  TAG: esi_parser	libxml2|expat|custom
#	ESI markup is not strictly XML compatible. The custom ESI parser
#	will give higher performance, but cannot handle non ASCII character encodings.
#Default:
# esi_parser custom

# DELAY POOL PARAMETERS
# -----------------------------------------------------------------------------

#  TAG: delay_pools
#	This represents the number of delay pools to be used.  For example,
#	if you have one class 2 delay pool and one class 3 delays pool, you
#	have a total of 2 delay pools.
#Default:
# delay_pools 0

#  TAG: delay_class
#	This defines the class of each delay pool.  There must be exactly one
#	delay_class line for each delay pool.  For example, to define two
#	delay pools, one of class 2 and one of class 3, the settings above
#	and here would be:
#
#	Example:
#	    delay_pools 4      # 4 delay pools
#	    delay_class 1 2    # pool 1 is a class 2 pool
#	    delay_class 2 3    # pool 2 is a class 3 pool
#	    delay_class 3 4    # pool 3 is a class 4 pool
#	    delay_class 4 5    # pool 4 is a class 5 pool
#
#	The delay pool classes are:
#
#		class 1		Everything is limited by a single aggregate
#				bucket.
#
#		class 2 	Everything is limited by a single aggregate
#				bucket as well as an "individual" bucket chosen
#				from bits 25 through 32 of the IPv4 address.
#
#		class 3		Everything is limited by a single aggregate
#				bucket as well as a "network" bucket chosen
#				from bits 17 through 24 of the IP address and a
#				"individual" bucket chosen from bits 17 through
#				32 of the IPv4 address.
#
#		class 4		Everything in a class 3 delay pool, with an
#				additional limit on a per user basis. This
#				only takes effect if the username is established
#				in advance - by forcing authentication in your
#				http_access rules.
#
#		class 5		Requests are grouped according their tag (see
#				external_acl's tag= reply).
#
#	NOTE: If an IP address is a.b.c.d
#		-> bits 25 through 32 are "d"
#		-> bits 17 through 24 are "c"
#		-> bits 17 through 32 are "c * 256 + d"
#
#	NOTE-2: Due to the use of bitmasks in class 2,3,4 pools they only apply to
#		IPv4 traffic. Class 1 and 5 pools may be used with IPv6 traffic.
#Default:
# none

#  TAG: delay_access
#	This is used to determine which delay pool a request falls into.
#
#	delay_access is sorted per pool and the matching starts with pool 1,
#	then pool 2, ..., and finally pool N. The first delay pool where the
#	request is allowed is selected for the request. If it does not allow
#	the request to any pool then the request is not delayed (default).
#
#	For example, if you want some_big_clients in delay
#	pool 1 and lotsa_little_clients in delay pool 2:
#
#Example:
# delay_access 1 allow some_big_clients
# delay_access 1 deny all
# delay_access 2 allow lotsa_little_clients
# delay_access 2 deny all
# delay_access 3 allow authenticated_clients
#Default:
# none

#  TAG: delay_parameters
#	This defines the parameters for a delay pool.  Each delay pool has
#	a number of "buckets" associated with it, as explained in the
#	description of delay_class.  For a class 1 delay pool, the syntax is:
#
#delay_parameters pool aggregate
#
#	For a class 2 delay pool:
#
#delay_parameters pool aggregate individual
#
#	For a class 3 delay pool:
#
#delay_parameters pool aggregate network individual
#
#	For a class 4 delay pool:
#
#delay_parameters pool aggregate network individual user
#
#	For a class 5 delay pool:
#
#delay_parameters pool tag
#
#	The variables here are:
#
#		pool		a pool number - ie, a number between 1 and the
#				number specified in delay_pools as used in
#				delay_class lines.
#
#		aggregate	the "delay parameters" for the aggregate bucket
#				(class 1, 2, 3).
#
#		individual	the "delay parameters" for the individual
#				buckets (class 2, 3).
#
#		network		the "delay parameters" for the network buckets
#				(class 3).
#
#		user		the delay parameters for the user buckets
#				(class 4).
#
#		tag		the delay parameters for the tag buckets
#				(class 5).
#
#	A pair of delay parameters is written restore/maximum, where restore is
#	the number of bytes (not bits - modem and network speeds are usually
#	quoted in bits) per second placed into the bucket, and maximum is the
#	maximum number of bytes which can be in the bucket at any time.
#
#	For example, if delay pool number 1 is a class 2 delay pool as in the
#	above example, and is being used to strictly limit each host to 64kbps
#	(plus overheads), with no overall limit, the line is:
#
#delay_parameters 1 -1/-1 8000/8000
#
#	Note that the figure -1 is used to represent "unlimited".
#
#	And, if delay pool number 2 is a class 3 delay pool as in the above
#	example, and you want to limit it to a total of 256kbps (strict limit)
#	with each 8-bit network permitted 64kbps (strict limit) and each
#	individual host permitted 4800bps with a bucket maximum size of 64kb
#	to permit a decent web page to be downloaded at a decent speed
#	(if the network is not being limited due to overuse) but slow down
#	large downloads more significantly:
#
#delay_parameters 2 32000/32000 8000/8000 600/8000
#
#	There must be one delay_parameters line for each delay pool.
#
#	Finally, for a class 4 delay pool as in the example - each user will
#	be limited to 128Kb no matter how many workstations they are logged into.:
#
#delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
#Default:
# none

#  TAG: delay_initial_bucket_level	(percent, 0-100)
#	The initial bucket percentage is used to determine how much is put
#	in each bucket when squid starts, is reconfigured, or first notices
#	a host accessing it (in class 2 and class 3, individual hosts and
#	networks only have buckets associated with them once they have been
#	"seen" by squid).
#Default:
# delay_initial_bucket_level 50

# WCCPv1 AND WCCPv2 CONFIGURATION OPTIONS
# -----------------------------------------------------------------------------

#  TAG: wccp_router
#	Use this option to define your WCCP ``home'' router for
#	Squid.
#
#	wccp_router supports a single WCCP(v1) router
#
#	wccp2_router supports multiple WCCPv2 routers
#
#	only one of the two may be used at the same time and defines
#	which version of WCCP to use.
#Default:
# wccp_router any_addr

#  TAG: wccp2_router
#	Use this option to define your WCCP ``home'' router for
#	Squid.
#
#	wccp_router supports a single WCCP(v1) router
#
#	wccp2_router supports multiple WCCPv2 routers
#
#	only one of the two may be used at the same time and defines
#	which version of WCCP to use.
#Default:
# none

#  TAG: wccp_version
#	This directive is only relevant if you need to set up WCCP(v1)
#	to some very old and end-of-life Cisco routers. In all other
#	setups it must be left unset or at the default setting.
#	It defines an internal version in the WCCP(v1) protocol,
#	with version 4 being the officially documented protocol.
#
#	According to some users, Cisco IOS 11.2 and earlier only
#	support WCCP version 3.  If you're using that or an earlier
#	version of IOS, you may need to change this value to 3, otherwise
#	do not specify this parameter.
#Default:
# wccp_version 4

#  TAG: wccp2_rebuild_wait
#	If this is enabled Squid will wait for the cache dir rebuild to finish
#	before sending the first wccp2 HereIAm packet
#Default:
# wccp2_rebuild_wait on

#  TAG: wccp2_forwarding_method
#	WCCP2 allows the setting of forwarding methods between the
#	router/switch and the cache.  Valid values are as follows:
#
#	gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
#	l2  - L2 redirect (forward the packet using Layer 2/MAC rewriting)
#
#	Currently (as of IOS 12.4) cisco routers only support GRE.
#	Cisco switches only support the L2 redirect assignment method.
#Default:
# wccp2_forwarding_method gre

#  TAG: wccp2_return_method
#	WCCP2 allows the setting of return methods between the
#	router/switch and the cache for packets that the cache
#	decides not to handle.  Valid values are as follows:
#
#	gre - GRE encapsulation (forward the packet in a GRE/WCCP tunnel)
#	l2  - L2 redirect (forward the packet using Layer 2/MAC rewriting)
#
#	Currently (as of IOS 12.4) cisco routers only support GRE.
#	Cisco switches only support the L2 redirect assignment.
#
#	If the "ip wccp redirect exclude in" command has been
#	enabled on the cache interface, then it is still safe for
#	the proxy server to use a l2 redirect method even if this
#	option is set to GRE.
#Default:
# wccp2_return_method gre

#  TAG: wccp2_assignment_method
#	WCCP2 allows the setting of methods to assign the WCCP hash
#	Valid values are as follows:
#
#	hash - Hash assignment
#	mask  - Mask assignment
#
#	As a general rule, cisco routers support the hash assignment method
#	and cisco switches support the mask assignment method.
#Default:
# wccp2_assignment_method hash

#  TAG: wccp2_service
#	WCCP2 allows for multiple traffic services. There are two
#	types: "standard" and "dynamic". The standard type defines
#	one service id - http (id 0). The dynamic service ids can be from
#	51 to 255 inclusive.  In order to use a dynamic service id
#	one must define the type of traffic to be redirected; this is done
#	using the wccp2_service_info option.
#
#	The "standard" type does not require a wccp2_service_info option,
#	just specifying the service id will suffice.
#
#	MD5 service authentication can be enabled by adding
#	"password=<password>" to the end of this service declaration.
#
#	Examples:
#
#	wccp2_service standard 0	# for the 'web-cache' standard service
#	wccp2_service dynamic 80	# a dynamic service type which will be
#					# fleshed out with subsequent options.
#	wccp2_service standard 0 password=foo
#Default:
# wccp2_service standard 0

#  TAG: wccp2_service_info
#	Dynamic WCCPv2 services require further information to define the
#	traffic you wish to have diverted.
#
#	The format is:
#
#	wccp2_service_info <id> protocol=<protocol> flags=<flag>,<flag>..
#	    priority=<priority> ports=<port>,<port>..
#
#	The relevant WCCPv2 flags:
#	+ src_ip_hash, dst_ip_hash
#	+ source_port_hash, dst_port_hash
#	+ src_ip_alt_hash, dst_ip_alt_hash
#	+ src_port_alt_hash, dst_port_alt_hash
#	+ ports_source
#
#	The port list can be one to eight entries.
#
#	Example:
#
#	wccp2_service_info 80 protocol=tcp flags=src_ip_hash,ports_source
#	    priority=240 ports=80
#
#	Note: the service id must have been defined by a previous
#	'wccp2_service dynamic <id>' entry.
#Default:
# none

#  TAG: wccp2_weight
#	Each cache server gets assigned a set of the destination
#	hash proportional to their weight.
#Default:
# wccp2_weight 10000

#  TAG: wccp_address
#  TAG: wccp2_address
#	Use this option if you require WCCP to use a specific
#	interface address.
#
#	The default behavior is to not bind to any specific address.
#Default:
# wccp_address 0.0.0.0
# wccp2_address 0.0.0.0

# PERSISTENT CONNECTION HANDLING
# -----------------------------------------------------------------------------
#
# Also see "pconn_timeout" in the TIMEOUTS section

#  TAG: client_persistent_connections
#  TAG: server_persistent_connections
#	Persistent connection support for clients and servers.  By
#	default, Squid uses persistent connections (when allowed)
#	with its clients and servers.  You can use these options to
#	disable persistent connections with clients and/or servers.
#Default:
# client_persistent_connections on
# server_persistent_connections on

#  TAG: persistent_connection_after_error
#	With this directive the use of persistent connections after
#	HTTP errors can be disabled. Useful if you have clients
#	who fail to handle errors on persistent connections proper.
#Default:
# persistent_connection_after_error off

#  TAG: detect_broken_pconn
#	Some servers have been found to incorrectly signal the use
#	of HTTP/1.0 persistent connections even on replies not
#	compatible, causing significant delays. This server problem
#	has mostly been seen on redirects.
#
#	By enabling this directive Squid attempts to detect such
#	broken replies and automatically assume the reply is finished
#	after 10 seconds timeout.
#Default:
# detect_broken_pconn off

# CACHE DIGEST OPTIONS
# -----------------------------------------------------------------------------

#  TAG: digest_generation
#	This controls whether the server will generate a Cache Digest
#	of its contents.  By default, Cache Digest generation is
#	enabled if Squid is compiled with --enable-cache-digests defined.
#Default:
# digest_generation on

#  TAG: digest_bits_per_entry
#	This is the number of bits of the server's Cache Digest which
#	will be associated with the Digest entry for a given HTTP
#	Method and URL (public key) combination.  The default is 5.
#Default:
# digest_bits_per_entry 5

#  TAG: digest_rebuild_period	(seconds)
#	This is the wait time between Cache Digest rebuilds.
#Default:
# digest_rebuild_period 1 hour

#  TAG: digest_rewrite_period	(seconds)
#	This is the wait time between Cache Digest writes to
#	disk.
#Default:
# digest_rewrite_period 1 hour

#  TAG: digest_swapout_chunk_size	(bytes)
#	This is the number of bytes of the Cache Digest to write to
#	disk at a time.  It defaults to 4096 bytes (4KB), the Squid
#	default swap page.
#Default:
# digest_swapout_chunk_size 4096 bytes

#  TAG: digest_rebuild_chunk_percentage	(percent, 0-100)
#	This is the percentage of the Cache Digest to be scanned at a
#	time.  By default it is set to 10% of the Cache Digest.
#Default:
# digest_rebuild_chunk_percentage 10

# SNMP OPTIONS
# -----------------------------------------------------------------------------

#  TAG: snmp_access
#	Allowing or denying access to the SNMP port.
#
#	All access to the agent is denied by default.
#	usage:
#
#	snmp_access allow|deny [!]aclname ...
#
#	This clause only supports fast acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#Example:
# snmp_access allow snmppublic localhost
# snmp_access deny all
#Default:
# snmp_access deny all
##EOLE
snmp_access allow snmppublic lxcroot
snmp_access allow snmppublic localhost
snmp_access deny all

#  TAG: snmp_incoming_address
#  TAG: snmp_outgoing_address
#	Just like 'udp_incoming_address', but for the SNMP port.
#
#	snmp_incoming_address	is used for the SNMP socket receiving
#				messages from SNMP agents.
#	snmp_outgoing_address	is used for SNMP packets returned to SNMP
#				agents.
#
#	The default snmp_incoming_address is to listen on all
#	available network interfaces.
#
#	If snmp_outgoing_address is not set it will use the same socket
#	as snmp_incoming_address. Only change this if you want to have
#	SNMP replies sent using another address than where this Squid
#	listens for SNMP queries.
#
#	NOTE, snmp_incoming_address and snmp_outgoing_address can not have
#	the same value since they both use port 3401.
#Default:
# snmp_incoming_address any_addr
# snmp_outgoing_address no_addr
##EOLE
snmp_incoming_address %%container_ip_proxy
#snmp_outgoing_address 255.255.255.255

# ICP OPTIONS
# -----------------------------------------------------------------------------

#  TAG: icp_port
#	The port number where Squid sends and receives ICP queries to
#	and from neighbor caches.  The standard UDP port for ICP is 3130.
#	Default is disabled (0).
#
#	Example:
#		icp_port 3130
#Default:
# icp_port 0
icp_port %%icp_port

#  TAG: htcp_port
#	The port number where Squid sends and receives HTCP queries to
#	and from neighbor caches.  To turn it on you want to set it to
#	4827. By default it is set to "0" (disabled).
#
#	Example:
#		htcp_port 4827
#Default:
# htcp_port 0
htcp_port %%htcp_port

#  TAG: log_icp_queries	on|off
#	If set, ICP queries are logged to access.log. You may wish
#	do disable this if your ICP load is VERY high to speed things
#	up or to simplify log analysis.
#Default:
# log_icp_queries on

#  TAG: udp_incoming_address
#	udp_incoming_address	is used for UDP packets received from other
#				caches.
#
#	The default behavior is to not bind to any specific address.
#
#	Only change this if you want to have all UDP queries received on
#	a specific interface/address.
#
#	NOTE: udp_incoming_address is used by the ICP, HTCP, and DNS
#	modules. Altering it will affect all of them in the same manner.
#
#	see also; udp_outgoing_address
#
#	NOTE, udp_incoming_address and udp_outgoing_address can not
#	have the same value since they both use the same port.
#Default:
# udp_incoming_address any_addr
#udp_incoming_address

#  TAG: udp_outgoing_address
#	udp_outgoing_address	is used for UDP packets sent out to other
#				caches.
#
#	The default behavior is to not bind to any specific address.
#
#	Instead it will use the same socket as udp_incoming_address.
#	Only change this if you want to have UDP queries sent using another
#	address than where this Squid listens for UDP queries from other
#	caches.
#
#	NOTE: udp_outgoing_address is used by the ICP, HTCP, and DNS
#	modules. Altering it will affect all of them in the same manner.
#
#	see also; udp_incoming_address
#
#	NOTE, udp_incoming_address and udp_outgoing_address can not
#	have the same value since they both use the same port.
#Default:
# udp_outgoing_address no_addr
#udp_outgoing_address

#  TAG: icp_hit_stale	on|off
#	If you want to return ICP_HIT for stale cache objects, set this
#	option to 'on'.  If you have sibling relationships with caches
#	in other administrative domains, this should be 'off'.  If you only
#	have sibling relationships with caches under your control,
#	it is probably okay to set this to 'on'.
#	If set to 'on', your siblings should use the option "allow-miss"
#	on their cache_peer lines for connecting to you.
#Default:
# icp_hit_stale off

#  TAG: minimum_direct_hops
#	If using the ICMP pinging stuff, do direct fetches for sites
#	which are no more than this many hops away.
#Default:
# minimum_direct_hops 4

#  TAG: minimum_direct_rtt
#	If using the ICMP pinging stuff, do direct fetches for sites
#	which are no more than this many rtt milliseconds away.
#Default:
# minimum_direct_rtt 400

#  TAG: netdb_low
#  TAG: netdb_high
#	The low and high water marks for the ICMP measurement
#	database.  These are counts, not percents.  The defaults are
#	900 and 1000.  When the high water mark is reached, database
#	entries will be deleted until the low mark is reached.
#Default:
# netdb_low 900
# netdb_high 1000

#  TAG: netdb_ping_period
#	The minimum period for measuring a site.  There will be at
#	least this much delay between successive pings to the same
#	network.  The default is five minutes.
#Default:
# netdb_ping_period 5 minutes

#  TAG: query_icmp	on|off
#	If you want to ask your peers to include ICMP data in their ICP
#	replies, enable this option.
#
#	If your peer has configured Squid (during compilation) with
#	'--enable-icmp' that peer will send ICMP pings to origin server
#	sites of the URLs it receives.  If you enable this option the
#	ICP replies from that peer will include the ICMP data (if available).
#	Then, when choosing a parent cache, Squid will choose the parent with
#	the minimal RTT to the origin server.  When this happens, the
#	hierarchy field of the access.log will be
#	"CLOSEST_PARENT_MISS".  This option is off by default.
#Default:
# query_icmp off

#  TAG: test_reachability	on|off
#	When this is 'on', ICP MISS replies will be ICP_MISS_NOFETCH
#	instead of ICP_MISS if the target host is NOT in the ICMP
#	database, or has a zero RTT.
#Default:
# test_reachability off

#  TAG: icp_query_timeout	(msec)
#	Normally Squid will automatically determine an optimal ICP
#	query timeout value based on the round-trip-time of recent ICP
#	queries.  If you want to override the value determined by
#	Squid, set this 'icp_query_timeout' to a non-zero value.  This
#	value is specified in MILLISECONDS, so, to use a 2-second
#	timeout (the old default), you would write:
#
#		icp_query_timeout 2000
#Default:
# icp_query_timeout 0
icp_query_timeout %%icp_query_timeout

#  TAG: maximum_icp_query_timeout	(msec)
#	Normally the ICP query timeout is determined dynamically.  But
#	sometimes it can lead to very large values (say 5 seconds).
#	Use this option to put an upper limit on the dynamic timeout
#	value.  Do NOT use this option to always use a fixed (instead
#	of a dynamic) timeout value. To set a fixed timeout see the
#	'icp_query_timeout' directive.
#Default:
# maximum_icp_query_timeout 2000
maximum_icp_query_timeout %%maximum_icp_query_timeout

#  TAG: minimum_icp_query_timeout	(msec)
#	Normally the ICP query timeout is determined dynamically.  But
#	sometimes it can lead to very small timeouts, even lower than
#	the normal latency variance on your link due to traffic.
#	Use this option to put an lower limit on the dynamic timeout
#	value.  Do NOT use this option to always use a fixed (instead
#	of a dynamic) timeout value. To set a fixed timeout see the
#	'icp_query_timeout' directive.
#Default:
# minimum_icp_query_timeout 5

#  TAG: background_ping_rate	time-units
#	Controls how often the ICP pings are sent to siblings that
#	have background-ping set.
#Default:
# background_ping_rate 10 seconds

# MULTICAST ICP OPTIONS
# -----------------------------------------------------------------------------

#  TAG: mcast_groups
#	This tag specifies a list of multicast groups which your server
#	should join to receive multicasted ICP queries.
#
#	NOTE!  Be very careful what you put here!  Be sure you
#	understand the difference between an ICP _query_ and an ICP
#	_reply_.  This option is to be set only if you want to RECEIVE
#	multicast queries.  Do NOT set this option to SEND multicast
#	ICP (use cache_peer for that).  ICP replies are always sent via
#	unicast, so this option does not affect whether or not you will
#	receive replies from multicast group members.
#
#	You must be very careful to NOT use a multicast address which
#	is already in use by another group of caches.
#
#	If you are unsure about multicast, please read the Multicast
#	chapter in the Squid FAQ (http://www.squid-cache.org/FAQ/).
#
#	Usage: mcast_groups 239.128.16.128 224.0.1.20
#
#	By default, Squid doesn't listen on any multicast groups.
#Default:
# none
%if %%mcast_groups != ''
mcast_groups %%mcast_groups
%end if

#  TAG: mcast_miss_addr
# Note: This option is only available if Squid is rebuilt with the
#       -DMULTICAST_MISS_STREAM define
#
#	If you enable this option, every "cache miss" URL will
#	be sent out on the specified multicast address.
#
#	Do not enable this option unless you are are absolutely
#	certain you understand what you are doing.
#Default:
# mcast_miss_addr no_addr

#  TAG: mcast_miss_ttl
# Note: This option is only available if Squid is rebuilt with the
#       -DMULTICAST_MISS_STREAM define
#
#	This is the time-to-live value for packets multicasted
#	when multicasting off cache miss URLs is enabled.  By
#	default this is set to 'site scope', i.e. 16.
#Default:
# mcast_miss_ttl 16

#  TAG: mcast_miss_port
# Note: This option is only available if Squid is rebuilt with the
#       -DMULTICAST_MISS_STREAM define
#
#	This is the port number to be used in conjunction with
#	'mcast_miss_addr'.
#Default:
# mcast_miss_port 3135

#  TAG: mcast_miss_encode_key
# Note: This option is only available if Squid is rebuilt with the
#       -DMULTICAST_MISS_STREAM define
#
#	The URLs that are sent in the multicast miss stream are
#	encrypted.  This is the encryption key.
#Default:
# mcast_miss_encode_key XXXXXXXXXXXXXXXX

#  TAG: mcast_icp_query_timeout	(msec)
#	For multicast peers, Squid regularly sends out ICP "probes" to
#	count how many other peers are listening on the given multicast
#	address.  This value specifies how long Squid should wait to
#	count all the replies.  The default is 2000 msec, or 2
#	seconds.
#Default:
# mcast_icp_query_timeout 2000
mcast_icp_query_timeout %%mcast_icp_query_timeout

# INTERNAL ICON OPTIONS
# -----------------------------------------------------------------------------

#  TAG: icon_directory
#	Where the icons are stored. These are normally kept in
#	/usr/share/squid/icons
#Default:
# icon_directory /usr/share/squid/icons

#  TAG: global_internal_static
#	This directive controls is Squid should intercept all requests for
#	/squid-internal-static/ no matter which host the URL is requesting
#	(default on setting), or if nothing special should be done for
#	such URLs (off setting). The purpose of this directive is to make
#	icons etc work better in complex cache hierarchies where it may
#	not always be possible for all corners in the cache mesh to reach
#	the server generating a directory listing.
#Default:
# global_internal_static on

#  TAG: short_icon_urls
#	If this is enabled Squid will use short URLs for icons.
#	If disabled it will revert to the old behavior of including
#	it's own name and port in the URL.
#
#	If you run a complex cache hierarchy with a mix of Squid and
#	other proxies you may need to disable this directive.
#Default:
# short_icon_urls on

# ERROR PAGE OPTIONS
# -----------------------------------------------------------------------------

#  TAG: error_directory
#	If you wish to create your own versions of the default
#	error files to customize them to suit your company copy
#	the error/template files to another directory and point
#	this tag at them.
#
#	WARNING: This option will disable multi-language support
#	         on error pages if used.
#
#	The squid developers are interested in making squid available in
#	a wide variety of languages. If you are making translations for a
#	language that Squid does not currently provide please consider
#	contributing your translation back to the project.
#	http://wiki.squid-cache.org/Translations
#
#	The squid developers working on translations are happy to supply drop-in
#	translated error files in exchange for any new language contributions.
#Default:
# none

#  TAG: error_default_language
#	Set the default language which squid will send error pages in
#	if no existing translation matches the clients language
#	preferences.
#
#	If unset (default) generic English will be used.
#
#	The squid developers are interested in making squid available in
#	a wide variety of languages. If you are interested in making
#	translations for any language see the squid wiki for details.
#	http://wiki.squid-cache.org/Translations
#Default:
# none

#  TAG: error_log_languages
#	Log to cache.log what languages users are attempting to
#	auto-negotiate for translations.
#
#	Successful negotiations are not logged. Only failures
#	have meaning to indicate that Squid may need an upgrade
#	of its error page translations.
#Default:
# error_log_languages on

#  TAG: err_page_stylesheet
#	CSS Stylesheet to pattern the display of Squid default error pages.
#
#	For information on CSS see http://www.w3.org/Style/CSS/
#Default:
# err_page_stylesheet /etc/squid/errorpage.css

#  TAG: err_html_text
#	HTML text to include in error messages.  Make this a "mailto"
#	URL to your admin address, or maybe just a link to your
#	organizations Web page.
#
#	To include this in your error messages, you must rewrite
#	the error template files (found in the "errors" directory).
#	Wherever you want the 'err_html_text' line to appear,
#	insert a %L tag in the error template file.
#Default:
# none

#  TAG: email_err_data	on|off
#	If enabled, information about the occurred error will be
#	included in the mailto links of the ERR pages (if %W is set)
#	so that the email body contains the data.
#	Syntax is <A HREF="mailto:%w%W">%w</A>
#Default:
# email_err_data on

#  TAG: deny_info
#	Usage:   deny_info err_page_name acl
#	or       deny_info http://... acl
#	or       deny_info TCP_RESET acl
#
#	This can be used to return a ERR_ page for requests which
#	do not pass the 'http_access' rules.  Squid remembers the last
#	acl it evaluated in http_access, and if a 'deny_info' line exists
#	for that ACL Squid returns a corresponding error page.
#
#	The acl is typically the last acl on the http_access deny line which
#	denied access. The exceptions to this rule are:
#	- When Squid needs to request authentication credentials. It's then
#	  the first authentication related acl encountered
#	- When none of the http_access lines matches. It's then the last
#	  acl processed on the last http_access line.
#
#	NP: If providing your own custom error pages with error_directory
#	    you may also specify them by your custom file name:
#	    Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
#
#	Alternatively you can specify an error URL. The browsers will
#	get redirected (302) to the specified URL. %s in the redirection
#	URL will be replaced by the requested URL.
#
#	Alternatively you can tell Squid to reset the TCP connection
#	by specifying TCP_RESET.
#Default:
# none

# OPTIONS INFLUENCING REQUEST FORWARDING
# -----------------------------------------------------------------------------

#  TAG: nonhierarchical_direct
#	By default, Squid will send any non-hierarchical requests
#	(matching hierarchy_stoplist or not cacheable request type) direct
#	to origin servers.
#
#	If you set this to off, Squid will prefer to send these
#	requests to parents.
#
#	Note that in most configurations, by turning this off you will only
#	add latency to these request without any improvement in global hit
#	ratio.
#
#	If you are inside an firewall see never_direct instead of
#	this directive.
#Default:
# nonhierarchical_direct on

#  TAG: prefer_direct
#	Normally Squid tries to use parents for most requests. If you for some
#	reason like it to first try going direct and only use a parent if
#	going direct fails set this to on.
#
#	By combining nonhierarchical_direct off and prefer_direct on you
#	can set up Squid to use a parent as a backup path if going direct
#	fails.
#
#	Note: If you want Squid to use parents for all requests see
#	the never_direct directive. prefer_direct only modifies how Squid
#	acts on cacheable requests.
#Default:
# prefer_direct off

#  TAG: always_direct
#	Usage: always_direct allow|deny [!]aclname ...
#
#	Here you can use ACL elements to specify requests which should
#	ALWAYS be forwarded by Squid to the origin servers without using
#	any peers.  For example, to always directly forward requests for
#	local servers ignoring any parents or siblings you may have use
#	something like:
#
#		acl local-servers dstdomain my.domain.net
#		always_direct allow local-servers
#
#	To always forward FTP requests directly, use
#
#		acl FTP proto FTP
#		always_direct allow FTP
#
#	NOTE: There is a similar, but opposite option named
#	'never_direct'.  You need to be aware that "always_direct deny
#	foo" is NOT the same thing as "never_direct allow foo".  You
#	may need to use a deny rule to exclude a more-specific case of
#	some other rule.  Example:
#
#		acl local-external dstdomain external.foo.net
#		acl local-servers dstdomain  .foo.net
#		always_direct deny local-external
#		always_direct allow local-servers
#
#	NOTE: If your goal is to make the client forward the request
#	directly to the origin server bypassing Squid then this needs
#	to be done in the client configuration. Squid configuration
#	can only tell Squid how Squid should fetch the object.
#
#	NOTE: This directive is not related to caching. The replies
#	is cached as usual even if you use always_direct. To not cache
#	the replies see the 'cache' directive.
#
#	This clause supports both fast and slow acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#Default:
# none

#  TAG: never_direct
#	Usage: never_direct allow|deny [!]aclname ...
#
#	never_direct is the opposite of always_direct.  Please read
#	the description for always_direct if you have not already.
#
#	With 'never_direct' you can use ACL elements to specify
#	requests which should NEVER be forwarded directly to origin
#	servers.  For example, to force the use of a proxy for all
#	requests, except those in your local domain use something like:
#
#		acl local-servers dstdomain .foo.net
#		never_direct deny local-servers
#		never_direct allow all
#
#	or if Squid is inside a firewall and there are local intranet
#	servers inside the firewall use something like:
#
#		acl local-intranet dstdomain .foo.net
#		acl local-external dstdomain external.foo.net
#		always_direct deny local-external
#		always_direct allow local-intranet
#		never_direct allow all
#
#	This clause supports both fast and slow acl types.
#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.

#  TAG: accept_filter
#	FreeBSD:
#
#	The name of an accept(2) filter to install on Squid's
#	listen socket(s).  This feature is perhaps specific to
#	FreeBSD and requires support in the kernel.
#
#	The 'httpready' filter delays delivering new connections
#	to Squid until a full HTTP request has been received.
#	See the accf_http(9) man page for details.
#
#	The 'dataready' filter delays delivering new connections
#	to Squid until there is some data to process.
#	See the accf_dataready(9) man page for details.
#
#	Linux:
#
#	The 'data' filter delays delivering of new connections
#	to Squid until there is some data to process by TCP_ACCEPT_DEFER.
#	You may optionally specify a number of seconds to wait by
#	'data=N' where N is the number of seconds. Defaults to 30
#	if not specified.  See the tcp(7) man page for details.
#EXAMPLE:
## FreeBSD
#accept_filter httpready
## Linux
#accept_filter data
#Default:
# none

#  TAG: client_ip_max_connections
#	Set an absolute limit on the number of connections a single
#	client IP can use. Any more than this and Squid will begin to drop
#	new connections from the client until it closes some links.
#
#	Note that this is a global limit. It affects all HTTP, HTCP, Gopher and FTP
#	connections from the client. For finer control use the ACL access controls.
#
#	Requires client_db to be enabled (the default).
#
#	WARNING: This may noticably slow down traffic received via external proxies
#	or NAT devices and cause them to rebound error messages back to their clients.
#Default:
# client_ip_max_connections -1

#  TAG: tcp_recv_bufsize	(bytes)
#	Size of receive buffer to set for TCP sockets.  Probably just
#	as easy to change your kernel's default.  Set to zero to use
#	the default buffer size.
#Default:
# tcp_recv_bufsize 0 bytes



# eCAP OPTIONS
# -----------------------------------------------------------------------------

#  TAG: ecap_enable	on|off
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ecap option
#
#	Controls whether eCAP support is enabled.
#Default:
# ecap_enable off

#  TAG: ecap_service
# Note: This option is only available if Squid is rebuilt with the
#       --enable-ecap option
#
#	Defines a single eCAP service
#
#	ecap_service servicename vectoring_point bypass service_url
#
#	vectoring_point = reqmod_precache|reqmod_postcache|respmod_precache|respmod_postcache
#		This specifies at which point of transaction processing the
#		eCAP service should be activated. *_postcache vectoring points
#		are not yet supported.
#	bypass = 1|0
#		If set to 1, the eCAP service is treated as optional. If the
#		service cannot be reached or malfunctions, Squid will try to
#		ignore any errors and process the message as if the service
#		was not enabled. No all eCAP errors can be bypassed.
#		If set to 0, the eCAP service is treated as essential and all
#		eCAP errors will result in an error page returned to the
#		HTTP client.
#	service_url = ecap://vendor/service_name?custom&cgi=style&parameters=optional
#
#Example:
#ecap_service service_1 reqmod_precache 0 ecap://filters-R-us/leakDetector?on_error=block
#ecap_service service_2 respmod_precache 1 icap://filters-R-us/virusFilter?config=/etc/vf.cfg
#Default:
# none

#  TAG: loadable_modules
#	Instructs Squid to load the specified dynamic module(s) or activate
#	preloaded module(s).
#Example:
#loadable_modules /usr/lib/MinimalAdapter.so
#Default:
# none

# MESSAGE ADAPTATION OPTIONS
# -----------------------------------------------------------------------------

#  TAG: adaptation_service_set
#
#	Configures an ordered set of similar, redundant services. This is
#	useful when hot standby or backup adaptation servers are available.
#
#	    adaptation_service_set set_name service_name1 service_name2 ...
#
# 	The named services are used in the set declaration order. The first
#	applicable adaptation service from the set is used first. The next
#	applicable service is tried if and only if the transaction with the
#	previous service fails and the message waiting to be adapted is still
#	intact.
#
#	When adaptation starts, broken services are ignored as if they were
#	not a part of the set. A broken service is a down optional service.
#
#	The services in a set must be attached to the same vectoring point
#	(e.g., pre-cache) and use the same adaptation method (e.g., REQMOD).
#
#	If all services in a set are optional then adaptation failures are
#	bypassable. If all services in the set are essential, then a
#	transaction failure with one service may still be retried using
#	another service from the set, but when all services fail, the master
#	transaction fails as well.
#
#	A set may contain a mix of optional and essential services, but that
#	is likely to lead to surprising results because broken services become
#	ignored (see above), making previously bypassable failures fatal.
#	Technically, it is the bypassability of the last failed service that
#	matters.
#
#	See also: adaptation_access adaptation_service_chain
#
#Example:
#adaptation_service_set svcBlocker urlFilterPrimary urlFilterBackup
#adaptation service_set svcLogger loggerLocal loggerRemote
#Default:
# none

#  TAG: adaptation_service_chain
#
#	Configures a list of complementary services that will be applied
#	one-by-one, forming an adaptation chain or pipeline. This is useful
#	when Squid must perform different adaptations on the same message.
#
#	    adaptation_service_chain chain_name service_name1 svc_name2 ...
#
# 	The named services are used in the chain declaration order. The first
#	applicable adaptation service from the chain is used first. The next
#	applicable service is applied to the successful adaptation results of
#	the previous service in the chain.
#
#	When adaptation starts, broken services are ignored as if they were
#	not a part of the chain. A broken service is a down optional service.
#
#	Request satisfaction terminates the adaptation chain because Squid
#	does not currently allow declaration of RESPMOD services at the
#	"reqmod_precache" vectoring point (see icap_service or ecap_service).
#
#	The services in a chain must be attached to the same vectoring point
#	(e.g., pre-cache) and use the same adaptation method (e.g., REQMOD).
#
#	A chain may contain a mix of optional and essential services. If an
#	essential adaptation fails (or the failure cannot be bypassed for
#	other reasons), the master transaction fails. Otherwise, the failure
#	is bypassed as if the failed adaptation service was not in the chain.
#
#	See also: adaptation_access adaptation_service_set
#
#Example:
#adaptation_service_chain svcRequest requestLogger urlFilter leakDetector
#Default:
# none

#  TAG: adaptation_access
#	Sends an HTTP transaction to an ICAP or eCAP adaptation	service.
#
#	adaptation_access service_name allow|deny [!]aclname...
#	adaptation_access set_name     allow|deny [!]aclname...
#
#	At each supported vectoring point, the adaptation_access
#	statements are processed in the order they appear in this
#	configuration file. Statements pointing to the following services
#	are ignored (i.e., skipped without checking their ACL):
#
#	    - services serving different vectoring points
#	    - "broken-but-bypassable" services
#	    - "up" services configured to ignore such transactions
#              (e.g., based on the ICAP Transfer-Ignore header).
#
#        When a set_name is used, all services in the set are checked
#	using the same rules, to find the first applicable one. See
#	adaptation_service_set for details.
#
#	If an access list is checked and there is a match, the
#	processing stops: For an "allow" rule, the corresponding
#	adaptation service is used for the transaction. For a "deny"
#	rule, no adaptation service is activated.
#
#	It is currently not possible to apply more than one adaptation
#	service at the same vectoring point to the same HTTP transaction.
#
#        See also: icap_service and ecap_service
#
#Example:
#adaptation_access service_1 allow all
#Default:
# none

#  TAG: adaptation_service_iteration_limit
#	Limits the number of iterations allowed when applying adaptation
#	services to a message. If your longest adaptation set or chain
#	may have more than 16 services, increase the limit beyond its
#	default value of 16. If detecting infinite iteration loops sooner
#	is critical, make the iteration limit match the actual number
#	of services in your longest adaptation set or chain.
#
#	Infinite adaptation loops are most likely with routing services.
#
#	See also: icap_service routing=1
#Default:
# adaptation_service_iteration_limit 16

#  TAG: adaptation_masterx_shared_names
#	For each master transaction (i.e., the HTTP request and response
#	sequence, including all related ICAP and eCAP exchanges), Squid
#	maintains a table of metadata. The table entries are (name, value)
#	pairs shared among eCAP and ICAP exchanges. The table is destroyed
#	with the master transaction.
#
#	This option specifies the table entry names that Squid must accept
#	from and forward to the adaptation transactions.
#
#	An ICAP REQMOD or RESPMOD transaction may set an entry in the
#	shared table by returning an ICAP header field with a name
#	specified in adaptation_masterx_shared_names. Squid will store
#	and forward that ICAP header field to subsequent ICAP
#	transactions within the same master transaction scope.
#
#	Only one shared entry name is supported at this time.
#
#Example:
## share authentication information among ICAP services
#adaptation_masterx_shared_names X-Subscriber-ID
#Default:
# none

#  TAG: icap_retry
#	This ACL determines which retriable ICAP transactions are
#	retried. Transactions that received a complete ICAP response
#	and did not have to consume or produce HTTP bodies to receive
#	that response are usually retriable.
#
#	icap_retry allow|deny [!]aclname ...
#
#	Squid automatically retries some ICAP I/O timeouts and errors
#	due to persistent connection race conditions.
#
#	See also: icap_retry_limit
#Default:
# icap_retry deny all

#  TAG: icap_retry_limit
#	Limits the number of retries allowed. When set to zero (default),
#	no retries are allowed.
#
#	Communication errors due to persistent connection race
#	conditions are unavoidable, automatically retried, and do not
#	count against this limit.
#
#	See also: icap_retry
#Default:
# icap_retry_limit 0

# DNS OPTIONS
# -----------------------------------------------------------------------------

#  TAG: check_hostnames
#	For security and stability reasons Squid can check
#	hostnames for Internet standard RFC compliance. If you want
#	Squid to perform these checks turn this directive on.
#Default:
# check_hostnames off
check_hostnames %%check_hostname

#  TAG: allow_underscore
#	Underscore characters is not strictly allowed in Internet hostnames
#	but nevertheless used by many sites. Set this to off if you want
#	Squid to be strict about the standard.
#	This check is performed only when check_hostnames is set to on.
#Default:
# allow_underscore on
allow_underscore %%allow_underscore

#  TAG: cache_dns_program
# Note: This option is only available if Squid is rebuilt with the
#       --disable-internal-dns option
#
#	Specify the location of the executable for dnslookup process.
#Default:
# cache_dns_program /usr/lib/squid/dnsserver

#  TAG: dns_children
# Note: This option is only available if Squid is rebuilt with the
#       --disable-internal-dns option
#
#	The number of processes spawn to service DNS name lookups.
#	For heavily loaded caches on large servers, you should
#	probably increase this value to at least 10.  The maximum
#	is 32.  The default is 5.
#
#	You must have at least one dnsserver process.
#Default:
# dns_children 5

#  TAG: dns_retransmit_interval
#	Initial retransmit interval for DNS queries. The interval is
#	doubled each time all configured DNS servers have been tried.
#
#Default:
# dns_retransmit_interval 5 seconds

#  TAG: dns_timeout
#	DNS Query timeout. If no response is received to a DNS query
#	within this time all DNS servers for the queried domain
#	are assumed to be unavailable.
#Default:
# dns_timeout 2 minutes

#  TAG: dns_defnames	on|off
#	Normally the RES_DEFNAMES resolver option is disabled
#	(see res_init(3)).  This prevents caches in a hierarchy
#	from interpreting single-component hostnames locally.  To allow
#	Squid to handle single-component names, enable this option.
#Default:
# dns_defnames off
dns_defnames %%dns_defnames

#  TAG: dns_nameservers
#	Use this if you want to specify a list of DNS name servers
#	(IP addresses) to use instead of those given in your
#	/etc/resolv.conf file.
#	On Windows platforms, if no value is specified here or in
#	the /etc/resolv.conf file, the list of DNS name servers are
#	taken from the Windows registry, both static and dynamic DHCP
#	configurations are supported.
#
#	Example: dns_nameservers 10.0.0.1 192.172.0.4
#Default:
# none

#  TAG: hosts_file
#	Location of the host-local IP name-address associations
#	database. Most Operating Systems have such a file on different
#	default locations:
#	- Un*X & Linux:    /etc/hosts
#	- Windows NT/2000: %SystemRoot%\system32\drivers\etc\hosts
#			   (%SystemRoot% value install default is c:\winnt)
#	- Windows XP/2003: %SystemRoot%\system32\drivers\etc\hosts
#			   (%SystemRoot% value install default is c:\windows)
#	- Windows 9x/Me:   %windir%\hosts
#			   (%windir% value is usually c:\windows)
#	- Cygwin:	   /etc/hosts
#
#	The file contains newline-separated definitions, in the
#	form ip_address_in_dotted_form name [name ...] names are
#	whitespace-separated. Lines beginning with an hash (#)
#	character are comments.
#
#	The file is checked at startup and upon configuration.
#	If set to 'none', it won't be checked.
#	If append_domain is used, that domain will be added to
#	domain-local (i.e. not containing any dot character) host
#	definitions.
#Default:
# hosts_file /etc/hosts
hosts_file %%hosts_file

#  TAG: append_domain
#	Appends local domain name to hostnames without any dots in
#	them.  append_domain must begin with a period.
#
#	Be warned there are now Internet names with no dots in
#	them using only top-domain names, so setting this may
#	cause some Internet sites to become unavailable.
#
#Example:
# append_domain .yourdomain.com
#Default:
# none

#  TAG: ignore_unknown_nameservers
#	By default Squid checks that DNS responses are received
#	from the same IP addresses they are sent to.  If they
#	don't match, Squid ignores the response and writes a warning
#	message to cache.log.  You can allow responses from unknown
#	nameservers by setting this option to 'off'.
#Default:
# ignore_unknown_nameservers on

#  TAG: ipcache_size	(number of entries)
#  TAG: ipcache_low	(percent)
#  TAG: ipcache_high	(percent)
#	The size, low-, and high-water marks for the IP cache.
#Default:
# ipcache_size 1024
# ipcache_low 90
# ipcache_high 95
ipcache_size %%ipcache_size
ipcache_low %%ipcache_low
ipcache_high %%ipcache_high

#	Maximum number of FQDN cache entries.
#Default:
# fqdncache_size 1024
fqdncache_size %%fqdncache_size

# MISCELLANEOUS
# -----------------------------------------------------------------------------

#  TAG: memory_pools	on|off
#	If set, Squid will keep pools of allocated (but unused) memory
#	available for future use.  If memory is a premium on your
#	system and you believe your malloc library outperforms Squid
#	routines, disable this.
#Default:
# memory_pools on

#  TAG: memory_pools_limit	(bytes)
#	Used only with memory_pools on:
#	memory_pools_limit 50 MB
#
#	If set to a non-zero value, Squid will keep at most the specified
#	limit of allocated (but unused) memory in memory pools. All free()
#	requests that exceed this limit will be handled by your malloc
#	library. Squid does not pre-allocate any memory, just safe-keeps
#	objects that otherwise would be free()d. Thus, it is safe to set
#	memory_pools_limit to a reasonably high value even if your
#	configuration will use less memory.
#
#	If set to none, Squid will keep all memory it can. That is, there
#	will be no limit on the total amount of memory used for safe-keeping.
#
#	To disable memory allocation optimization, do not set
#	memory_pools_limit to 0. Set memory_pools to "off" instead.
#
#	An overhead for maintaining memory pools is not taken into account
#	when the limit is checked. This overhead is close to four bytes per
#	object kept. However, pools may actually _save_ memory because of
#	reduced memory thrashing in your malloc library.
#Default:
# memory_pools_limit 5 MB

#  TAG: forwarded_for	on|off|transparent|truncate|delete
#	If set to "on", Squid will append your client's IP address
#	in the HTTP requests it forwards. By default it looks like:
#
#		X-Forwarded-For: 192.1.2.3
#
#	If set to "off", it will appear as
#
#		X-Forwarded-For: unknown
#
#	If set to "transparent", Squid will not alter the
#	X-Forwarded-For header in any way.
#
#	If set to "delete", Squid will delete the entire
#	X-Forwarded-For header.
#
#	If set to "truncate", Squid will remove all existing
#	X-Forwarded-For entries, and place itself as the sole entry.
#Default:
# forwarded_for on
%if %%activer_filtrage_proxy == 'oui'
# X-Forwarded-For is already set by *guardian

#  TAG: cachemgr_passwd
#	Specify passwords for cachemgr operations.
#
#	Usage: cachemgr_passwd password action action ...
#
#	Some valid actions are (see cache manager menu for a full list):
#		5min
#		60min
#		asndb

#		store_digest
#		storedir
#		utilization
#		via_headers
#		vm_objects
#
#	* Indicates actions which will not be performed without a
#	  valid password, others can be performed if not listed here.
#
#	To disable an action, set the password to "disable".
#	To allow performing an action without a password, set the
#	password to "none".
#
#	Use the keyword "all" to set the same password for all actions.
#
#Example:
# cachemgr_passwd secret shutdown
# cachemgr_passwd lesssssssecret info stats/objects
# cachemgr_passwd disable all
#Default:
# none

#  TAG: client_db	on|off
#	If you want to disable collecting per-client statistics,
#	turn off client_db here.
#Default:
# client_db on

#  TAG: refresh_all_ims	on|off
#	When you enable this option, squid will always check
#	the origin server for an update when a client sends an
#	If-Modified-Since request.  Many browsers use IMS
#	requests when the user requests a reload, and this
#	ensures those clients receive the latest version.
#
#	By default (off), squid may return a Not Modified response
#	based on the age of the cached version.
#Default:
# refresh_all_ims off

#  TAG: reload_into_ims	on|off
#	When you enable this option, client no-cache or ``reload''
#	requests will be changed to If-Modified-Since requests.
#	Doing this VIOLATES the HTTP standard.  Enabling this
#	feature could make you liable for problems which it
#	causes.
#
#	see also refresh_pattern for a more selective approach.
#Default:
# reload_into_ims off

#  TAG: retry_on_error
#	If set to on Squid will automatically retry requests when
#	receiving an error response. This is mainly useful if you
#	are in a complex cache hierarchy to work around access
#	control errors.
#Default:
# retry_on_error off

#  TAG: as_whois_server
#	WHOIS server to query for AS numbers.  NOTE: AS numbers are
#	queried only when Squid starts up, not for every request.
#Default:
# as_whois_server whois.ra.net
# as_whois_server whois.ra.net

#  TAG: offline_mode
#	Enable this option and Squid will never try to validate cached
#	objects.
#Default:
# offline_mode off

#  TAG: uri_whitespace
#	What to do with requests that have whitespace characters in the
#	URI.  Options:
#
#	strip:  The whitespace characters are stripped out of the URL.
#		This is the behavior recommended by RFC2396.
#	deny:   The request is denied.  The user receives an "Invalid
#		Request" message.
#	allow:  The request is allowed and the URI is not changed.  The
#		whitespace characters remain in the URI.  Note the
#		whitespace is passed to redirector processes if they
#		are in use.
#	encode:	The request is allowed and the whitespace characters are
#		encoded according to RFC1738.  This could be considered
#		a violation of the HTTP/1.1
#		RFC because proxies are not allowed to rewrite URI's.
#	chop:	The request is allowed and the URI is chopped at the
#		first whitespace.  This might also be considered a
#		violation.
#Default:
# uri_whitespace strip

#  TAG: chroot
#	Specifies a directory where Squid should do a chroot() while
#	initializing.  This also causes Squid to fully drop root
#	privileges after initializing.  This means, for example, if you
#	use a HTTP port less than 1024 and try to reconfigure, you may
#	get an error saying that Squid can not open the port.
#Default:
# none

#  TAG: pipeline_prefetch
#	To boost the performance of pipelined requests to closer
#	match that of a non-proxied environment Squid can try to fetch
#	up to two requests in parallel from a pipeline.
#
#	Defaults to off for bandwidth management and access logging
#	reasons.
#Default:
# pipeline_prefetch off

#  TAG: high_response_time_warning	(msec)
#	If the one-minute median response time exceeds this value,
#	Squid prints a WARNING with debug level 0 to get the
#	administrators attention.  The value is in milliseconds.
#Default:
# high_response_time_warning 0

#  TAG: high_page_fault_warning
#	If the one-minute average page fault rate exceeds this
#	value, Squid prints a WARNING with debug level 0 to get
#	the administrators attention.  The value is in page faults
#	per second.
#Default:
# high_page_fault_warning 0

#  TAG: high_memory_warning
#	If the memory usage (as determined by mallinfo) exceeds
#	this amount, Squid prints a WARNING with debug level 0 to get
#	the administrators attention.
#Default:
# high_memory_warning 0 KB

#  TAG: sleep_after_fork	(microseconds)
#	When this is set to a non-zero value, the main Squid process
#	sleeps the specified number of microseconds after a fork()
#	system call. This sleep may help the situation where your
#	system reports fork() failures due to lack of (virtual)
#	memory. Note, however, if you have a lot of child
#	processes, these sleep delays will add up and your
#	Squid will not service requests for some amount of time
#	until all the child processes have been started.
#	On Windows value less then 1000 (1 milliseconds) are
#	rounded to 1000.
#Default:
# sleep_after_fork 0

#  TAG: windows_ipaddrchangemonitor	on|off
#	On Windows Squid by default will monitor IP address changes and will
#	reconfigure itself after any detected event. This is very useful for
#	proxies connected to internet with dial-up interfaces.
#	In some cases (a Proxy server acting as VPN gateway is one) it could be
#	desiderable to disable this behaviour setting this to 'off'.
#	Note: after changing this, Squid service must be restarted.
#Default:
# windows_ipaddrchangemonitor on

#  TAG: eui_lookup
#   Whether to lookup the EUI or MAC address of a connected client.
#Default:
# eui_lookup on

#  TAG: max_filedescriptors
#   Set the maximum number of filedescriptors, either below the
#   operating system default or up to the hard limit.
#
#   Remove from squid.conf to inherit the current ulimit soft
#   limit setting.
#
#   Note: Changing this requires a restart of Squid. Also
#   not all I/O types supports large values (eg on Windows).
#Default:
# Use operating system soft limit set by ulimit.
max_filedescriptors 65535

#  TAG: force_request_body_continuation
#   This option controls how Squid handles data upload requests from HTTP
#   and FTP agents that require a "Please Continue" control message response
#   to actually send the request body to Squid. It is mostly useful in
#   adaptation environments.
#
#   When Squid receives an HTTP request with an "Expect: 100-continue"
#   header or an FTP upload command (e.g., STOR), Squid normally sends the
#   request headers or FTP command information to an adaptation service (or
#   peer) and waits for a response. Most adaptation services (and some
#   broken peers) may not respond to Squid at that stage because they may
#   decide to wait for the HTTP request body or FTP data transfer. However,
#   that request body or data transfer may never come because Squid has not
#   responded with the HTTP 100 or FTP 150 (Please Continue) control message
#   to the request sender yet!
#
#   An allow match tells Squid to respond with the HTTP 100 or FTP 150
#   (Please Continue) control message on its own, before forwarding the
#   request to an adaptation service or peer. Such a response usually forces
#   the request sender to proceed with sending the body. A deny match tells
#   Squid to delay that control response until the origin server confirms
#   that the request body is needed. Delaying is the default behavior.
#Default:
# Deny, unless rules exist in squid.conf.

#  TAG: server_pconn_for_nonretriable
#   This option provides fine-grained control over persistent connection
#   reuse when forwarding HTTP requests that Squid cannot retry. It is useful
#   in environments where opening new connections is very expensive
#   (e.g., all connections are secured with TLS with complex client and server
#   certificate validation) and race conditions associated with persistent
#   connections are very rare and/or only cause minor problems.
#
#   HTTP prohibits retrying unsafe and non-idempotent requests (e.g., POST).
#   Squid limitations also prohibit retrying all requests with bodies (e.g., PUT).
#   By default, when forwarding such "risky" requests, Squid opens a new
#   connection to the server or cache_peer, even if there is an idle persistent
#   connection available. When Squid is configured to risk sending a non-retriable
#   request on a previously used persistent connection, and the server closes
#   the connection before seeing that risky request, the user gets an error response
#   from Squid. In most cases, that error response will be HTTP 502 (Bad Gateway)
#   with ERR_ZERO_SIZE_OBJECT or ERR_WRITE_ERROR (peer connection reset) error detail.
#
#   If an allow rule matches, Squid reuses an available idle persistent connection
#   (if any) for the request that Squid cannot retry. If a deny rule matches, then
#   Squid opens a new connection for the request that Squid cannot retry.
#
#   This option does not affect requests that Squid can retry. They will reuse idle
#   persistent connections (if any).
#
#   This clause only supports fast acl types.
#   See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details.
#
#   Example:
#       acl SpeedIsWorthTheRisk method POST
#       server_pconn_for_nonretriable allow SpeedIsWorthTheRisk
#Default:
# Open new connections for forwarding requests Squid cannot retry safely.
