+# WELCOME TO SQUID 2.7.STABLE6
+# ----------------------------
+#
+# This is the default Squid configuration file. You may wish
+# to look at the Squid home page (http://www.squid-cache.org/)
+# for the FAQ and other documentation.
+#
+# The default Squid config file shows what the defaults for
+# various options happen to be. If you don't need to change the
+# default, you shouldn't uncomment the line. Doing so may cause
+# run-time problems. In some cases "none" refers to no default
+# setting at all, while in other cases it refers to a valid
+# option - the comments for that keyword indicate if this is the
+# case.
+#
+
+
+# Configuration options can be included using the "include" directive.
+# Include takes a list of files to include. Quoting and wildcards is
+# supported.
+#
+# For example,
+#
+# include /path/to/included/file/squid.acl.config
+#
+# Includes can be nested up to a hard-coded depth of 16 levels.
+# This arbitrary restriction is to prevent recursive include references
+# from causing Squid entering an infinite loop whilst trying to load
+# configuration files.
+
+
+# OPTIONS FOR AUTHENTICATION
+# -----------------------------------------------------------------------------
+
+# TAG: auth_param
+# This is used to define parameters for the various authentication
+# schemes supported by Squid.
+#
+# format: auth_param scheme parameter [setting]
+#
+# The order in which authentication schemes are presented to the client is
+# dependent on the order the scheme first appears in config file. IE
+# has a bug (it's not RFC 2617 compliant) in that it will use the basic
+# scheme if basic is the first entry presented, even if more secure
+# schemes are presented. For now use the order in the recommended
+# settings section below. If other browsers have difficulties (don't
+# recognize the schemes offered even if you are using basic) either
+# put basic first, or disable the other schemes (by commenting out their
+# program entry).
+#
+# Once an authentication scheme is fully configured, it can only be
+# shutdown by shutting squid down and restarting. Changes can be made on
+# the fly and activated with a reconfigure. I.E. You can change to a
+# different helper, but not unconfigure the helper completely.
+#
+# Please note that while this directive defines how Squid processes
+# authentication it does not automatically activate authentication.
+# To use authentication you must in addition make use of ACLs based
+# on login name in http_access (proxy_auth, proxy_auth_regex or
+# external with %LOGIN used in the format tag). The browser will be
+# challenged for authentication on the first such acl encountered
+# in http_access processing and will also be re-challenged for new
+# login credentials if the request is being denied by a proxy_auth
+# type acl.
+#
+# WARNING: authentication can't be used in a transparently intercepting
+# proxy as the client then thinks it is talking to an origin server and
+# not the proxy. This is a limitation of bending the TCP/IP protocol to
+# transparently intercepting port 80, not a limitation in Squid.
+#
+# === Parameters for the basic scheme follow. ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username password" and replies "OK" or
+# "ERR" in an endless loop. "ERR" responses may optionally be followed
+# by a error description available as %m in the returned error page.
+#
+# By default, the basic authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use the traditional proxy authentication, jump over to
+# the helpers/basic_auth/NCSA directory and type:
+# % make
+# % make install
+#
+# Then, set this line to something like
+#
+# auth_param basic program /opt/csw/libexec/ncsa_auth /opt/csw/etc/passwd
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When credential verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param basic children 5
+#
+# "concurrency" numberofconcurrentrequests
+# The number of concurrent requests/channels the helper supports.
+# Changes the protocol used to include a channel number first on
+# the request/response line, allowing multiple requests to be sent
+# to the same helper in parallell without wating for the response.
+# Must not be set unless it's known the helper supports this.
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the client for
+# the basic proxy authentication scheme (part of the text the user
+# will see when prompted their username and password).
+# auth_param basic realm Squid proxy-caching web server
+#
+# "credentialsttl" timetolive
+# Specifies how long squid assumes an externally validated
+# username:password pair is valid for - in other words how often the
+# helper program is called for that user. Set this low to force
+# revalidation with short lived passwords. Note that setting this high
+# does not impact your susceptibility to replay attacks unless you are
+# using an one-time password system (such as SecureID). If you are using
+# such a system, you will be vulnerable to replay attacks unless you
+# also use the max_user_ip ACL in an http_access rule.
+# auth_param basic credentialsttl 2 hours
+#
+# "casesensitive" on|off
+# Specifies if usernames are case sensitive. Most user databases are
+# case insensitive allowing the same username to be spelled using both
+# lower and upper case letters, but some are case sensitive. This
+# makes a big difference for user_max_ip ACL processing and similar.
+# auth_param basic casesensitive off
+#
+# "blankpassword" on|off
+# Specifies if blank passwords should be supported. Defaults to off
+# as there is multiple authentication backends which handles blank
+# passwords as "guest" access.
+#
+# === Parameters for the digest scheme follow ===
+#
+# "program" cmdline
+# Specify the command for the external authenticator. Such a program
+# reads a line containing "username":"realm" and replies with the
+# appropriate H(A1) value hex encoded or ERR if the user (or his H(A1)
+# hash) does not exists. See RFC 2616 for the definition of H(A1).
+# "ERR" responses may optionally be followed by a error description
+# available as %m in the returned error page.
+#
+# By default, the digest authentication scheme is not used unless a
+# program is specified.
+#
+# If you want to use a digest authenticator, jump over to the
+# helpers/digest_auth/ directory and choose the authenticator to use.
+# It it's directory type
+# % make
+# % make install
+#
+# Then, set this line to something like
+#
+# auth_param digest program /opt/csw/libexec/digest_auth_pw /opt/csw/etc/digpass
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When credential verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param digest children 5
+#
+# "concurrency" numberofconcurrentrequests
+# The number of concurrent requests/channels the helper supports.
+# Changes the protocol used to include a channel number first on
+# the request/response line, allowing multiple requests to be sent
+# to the same helper in parallell without wating for the response.
+# Must not be set unless it's known the helper supports this.
+#
+# "realm" realmstring
+# Specifies the realm name which is to be reported to the client for the
+# digest proxy authentication scheme (part of the text the user will see
+# when prompted their username and password).
+# auth_param digest realm Squid proxy-caching web server
+#
+# "nonce_garbage_interval" timeinterval
+# Specifies the interval that nonces that have been issued to clients are
+# checked for validity.
+# auth_param digest nonce_garbage_interval 5 minutes
+#
+# "nonce_max_duration" timeinterval
+# Specifies the maximum length of time a given nonce will be valid for.
+# auth_param digest nonce_max_duration 30 minutes
+#
+# "nonce_max_count" number
+# Specifies the maximum number of times a given nonce can be used.
+# auth_param digest nonce_max_count 50
+#
+# "nonce_strictness" on|off
+# Determines if squid requires strict increment-by-1 behavior for nonce
+# counts, or just incrementing (off - for use when useragents generate
+# nonce counts that occasionally miss 1 (ie, 1,2,4,6)).
+# auth_param digest nonce_strictness off
+#
+# "check_nonce_count" on|off
+# This directive if set to off can disable the nonce count check
+# completely to work around buggy digest qop implementations in certain
+# mainstream browser versions. Default on to check the nonce count to
+# protect from authentication replay attacks.
+# auth_param digest check_nonce_count on
+#
+# "post_workaround" on|off
+# This is a workaround to certain buggy browsers who sends an incorrect
+# request digest in POST requests when reusing the same nonce as acquired
+# earlier in response to a GET request.
+# auth_param digest post_workaround off
+#
+# === NTLM scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external NTLM authenticator. Such a
+# program participates in the NTLMSSP exchanges between Squid and the
+# client and reads commands according to the Squid NTLMSSP helper
+# protocol. See helpers/ntlm_auth/ for details. Recommended ntlm
+# authenticator is ntlm_auth from Samba-3.X, but a number of other
+# ntlm authenticators is available.
+#
+# By default, the ntlm authentication scheme is not used unless a
+# program is specified.
+#
+# auth_param ntlm program /path/to/samba/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When credential verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param ntlm children 5
+#
+# "keep_alive" on|off
+# This option enables the use of keep-alive on the initial
+# authentication request. It has been reported some versions of MSIE
+# have problems if this is enabled, but performance will be increased
+# if enabled.
+#
+# auth_param ntlm keep_alive on
+#
+# === Negotiate scheme options follow ===
+#
+# "program" cmdline
+# Specify the command for the external Negotiate authenticator. Such a
+# program participates in the SPNEGO exchanges between Squid and the
+# client and reads commands according to the Squid ntlmssp helper
+# protocol. See helpers/ntlm_auth/ for details. Recommended SPNEGO
+# authenticator is ntlm_auth from Samba-4.X.
+#
+# By default, the Negotiate authentication scheme is not used unless a
+# program is specified.
+#
+# auth_param negotiate program /path/to/samba/bin/ntlm_auth --helper-protocol=gss-spnego
+#
+# "children" numberofchildren
+# The number of authenticator processes to spawn. If you start too few
+# squid will have to wait for them to process a backlog of credential
+# verifications, slowing it down. When credential verifications are
+# done via a (slow) network you are likely to need lots of
+# authenticator processes.
+# auth_param negotiate children 5
+#
+# "keep_alive" on|off
+# If you experience problems with PUT/POST requests when using the
+# Negotiate authentication scheme then you can try setting this to
+# off. This will cause Squid to forcibly close the connection on
+# the initial requests where the browser asks which schemes are
+# supported by the proxy.
+#
+# auth_param negotiate keep_alive on
+#
+#Recommended minimum configuration per scheme:
+#auth_param negotiate program <uncomment and complete this line to activate>
+#auth_param negotiate children 5
+#auth_param negotiate keep_alive on
+#auth_param ntlm program <uncomment and complete this line to activate>
+#auth_param ntlm children 5

+#auth_param basic program <uncomment and complete this line>
+#auth_param basic children 5
+#auth_param basic realm Squid proxy-caching web server
+#auth_param basic credentialsttl 2 hours
+#auth_param basic casesensitive off
+
+# TAG: authenticate_cache_garbage_interval
+# The time period between garbage collection across the username cache.
+# This is a tradeoff between memory utilization (long intervals - say
+# 2 days) and CPU (short intervals - say 1 minute). Only change if you
+# have good reason to.
+#
+#Default:
+# authenticate_cache_garbage_interval 1 hour
+
+# TAG: authenticate_ttl
+# The time a user & their credentials stay in the logged in user cache
+# since their last request. When the garbage interval passes, all user
+# credentials that have passed their TTL are removed from memory.
+#
+#Default:
+# authenticate_ttl 1 hour
+
+# TAG: authenticate_ip_ttl
+# If you use proxy authentication and the 'max_user_ip' ACL, this
+# directive controls how long Squid remembers the IP addresses
+# associated with each user. Use a small value (e.g., 60 seconds) if
+# your users might change addresses quickly, as is the case with
+# dialups. You might be safe using a larger value (e.g., 2 hours) in a
+# corporate LAN environment with relatively static address assignments.
+#
+#Default:
+# authenticate_ip_ttl 0 seconds
+
+# TAG: authenticate_ip_shortcircuit_ttl
+# Cache authentication credentials per client IP address for this
+# long. Default is 0 seconds (disabled).
+#
+# See also authenticate_ip_shortcircuit_access directive.
+#
+#Default:
+# authenticate_ip_shortcircuit_ttl 0 seconds

+# external_acl_type name [options] FORMAT.. /path/to/helper [helper arguments..]
+#
+# Options:
+#
+# ttl=n TTL in seconds for cached results (defaults to 3600
+# for 1 hour)
+# negative_ttl=n
+# TTL for cached negative lookups (default same
+# as ttl)

+# OK/ERR keyword=value ...
+#
+# Defined keywords:

+# user= The users name (login also understood)
+# password= The users password (for PROXYPASS login= cache_peer)
+# message= Error message or similar used as %o in error messages
+# (error also understood)
+# log= String to be logged in access.log. Available as
+# %ea in logformat specifications
+#
+# If protocol=3.0 (the default) then URL escaping is used to protect

+#
+# If using protocol=2.5 then all values need to be enclosed in quotes
+# if they may contain whitespace, or the whitespace escaped using \.
+# And quotes or \ characters within the keyword value must be \ escaped.
+#
+# When using the concurrency= option the protocol is changed by

+# The query channel tag is a number between 0 and concurrency-1.
+#
+# Compatibility Note: The children= option was named concurrency= in
+# Squid-2.5.STABLE3 and earlier, and was accepted as an alias for the
+# duration of the Squid-2.5 releases to keep compatibility. However,
+# the meaning of concurrency= option has changed in Squid-2.6 to match
+# that of Squid-3 and the old syntax no longer works.

+#
+# Allowing or Denying the X-Forwarded-For header to be followed to
+# find the original source of a request.
+#
+# Requests may pass through a chain of several other proxies
+# before reaching us. The X-Forwarded-For header will contain a
+# comma-separated list of the IP addresses in the chain, with the
+# rightmost address being the most recent.
+#
+# If a request reaches us from a source that is allowed by this
+# configuration item, then we consult the X-Forwarded-For header
+# to see where that host received the request from. If the
+# X-Forwarded-For header contains multiple addresses, and if
+# acl_uses_indirect_client is on, then we continue backtracking
+# until we reach an address for which we are not allowed to
+# follow the X-Forwarded-For header, or until we reach the first
+# address in the list. (If acl_uses_indirect_client is off, then
+# it's impossible to backtrack through more than one level of
+# X-Forwarded-For addresses.)
+#
+# The end result of this process is an IP address that we will
+# refer to as the indirect client address. This address may
+# be treated as the client address for access control, delay

+# If specified more than once, only the first is used.
+#
+# use 'round-robin' to define a set of parents which

+#
+# use 'carp' to define a set of parents which should

+#
+# 'multicast-responder' indicates the named peer
+# is a member of a multicast group. ICP queries will

+# will be accepted from it.
+#
+# the 'multicast-siblings' option is meant to be used
+# only for cache peers of type "multicast". It instructs
+# Squid that ALL members of this multicast group have
+# "sibling" relationship with it, not "parent". This is
+# an optimization that avoids useless multicast queries
+# to a multicast 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.
+#
+# 'closest-only' indicates that, for ICP_OP_MISS

+# Note: To combine this with local authentication the Basic
+# authentication scheme must be used, and both servers must

+#
+# use 'login=*:password' to pass the username to the

+#
+# NOTE: * Any number of domains may be given for a cache-host,

+#
+#Default:

+
+# 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

+# 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 8 MB
+
+# TAG: maximum_object_size_in_memory (bytes)
+# Objects greater than this size will not be attempted to kept in

+# 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

+#
+# Type specifies the kind of storage system to use. Only "ufs"
+# is built by default. To enable any of the other storage systems

+#
+# 'Directory' is a top-level directory where cache swap

+# The directory must exist and be writable by the Squid
+# process. Squid will NOT create this directory for you.
+# Only using COSS, a raw disk device or a stripe file can
+# be specified, but the configuration of the "cache_swap_log"

+# "ufs" is the old well-known Squid storage format that has always
+# been there.
+#
+# cache_dir ufs Directory-Name Mbytes L1 L2 [options]
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this
+# directory. The default is 100 MB. Change this to suit your
+# configuration. Do NOT put the size of your disk drive here.
+# Instead, if you want Squid to use the entire disk drive,
+# subtract 20% and use that value.
+#
+# 'Level-1' is the number of first-level subdirectories which
+# will be created under the 'Directory'. The default is 16.
+#
+# 'Level-2' is the number of second-level subdirectories which
+# will be created under each first-level directory. The default
+# is 256.
+#
+# The aufs store type:
+#
+# "aufs" uses the same storage format as "ufs", utilizing
+# POSIX-threads to avoid blocking the main Squid process on
+# disk-I/O. This was formerly known in Squid as async-io.
+#
+# cache_dir aufs Directory-Name Mbytes L1 L2 [options]
+#
+# see argument descriptions under ufs above

+# disk-I/O.
+#
+# cache_dir diskd Directory-Name Mbytes L1 L2 [options] [Q1=n] [Q2=n]
+#
+# see argument descriptions under ufs above
+#
+# Q1 specifies the number of unacknowledged I/O requests when Squid
+# stops opening new files. If this many messages are in the queues,
+# Squid won't open new files. Default is 64
+#
+# Q2 specifies the number of unacknowledged messages when Squid
+# starts blocking. If this many messages are in the queues,
+# Squid blocks until it receives some replies. Default is 72
+#
+# When Q1 < Q2 (the default), the cache directory is optimized
+# for lower response time at the expense of a decrease in hit

+# higher hit ratio at the expense of an increase in response
+# time.
+#
+# The coss store type:
+#
+# block-size=n defines the "block size" for COSS cache_dir's.
+# Squid uses file numbers as block numbers. Since file numbers
+# are limited to 24 bits, the block size determines the maximum
+# size of the COSS partition. The default is 512 bytes, which
+# leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
+# you should not change the COSS block size after Squid
+# has written some objects to the cache_dir.
+#
+# overwrite-percent=n defines the percentage of disk that COSS
+# must write to before a given object will be moved to the
+# current stripe. A value of "n" closer to 100 will cause COSS
+# to waste less disk space by having multiple copies of an object
+# on disk, but will increase the chances of overwriting a popular
+# object as COSS overwrites stripes. A value of "n" close to 0
+# will cause COSS to keep all current objects in the current COSS
+# stripe at the expense of the hit rate. The default value of 50
+# will allow any given object to be stored on disk a maximum of
+# 2 times.
+#
+# max-stripe-waste=n defines the maximum amount of space that COSS
+# will waste in a given stripe (in bytes). When COSS writes data
+# to disk, it will potentially waste up to "max-size" worth of disk
+# space for each 1MB of data written. If "max-size" is set to a
+# large value (ie >256k), this could potentially result in large
+# amounts of wasted disk space. Setting this value to a lower value
+# (ie 64k or 32k) will result in a COSS disk refusing to cache
+# larger objects until the COSS stripe has been filled to within
+# "max-stripe-waste" of the maximum size (1MB).
+#
+# membufs=n defines the number of "memory-only" stripes that COSS
+# will use. When an cache hit is performed on a COSS stripe before
+# COSS has reached the overwrite-percent value for that object,
+# COSS will use a series of memory buffers to hold the object in
+# while the data is sent to the client. This will define the maximum
+# number of memory-only buffers that COSS will use. The default value
+# is 10, which will use a maximum of 10MB of memory for buffers.
+#
+# maxfullbufs=n defines the maximum number of stripes a COSS partition
+# will have in memory waiting to be freed (either because the disk is
+# under load and the stripe is unwritten, or because clients are still
+# transferring data from objects using the memory). In order to try
+# and maintain a good hit rate under load, COSS will reserve the last
+# 2 full stripes for object hits. (ie a COSS cache_dir will reject
+# new objects when the number of full stripes is 2 less than maxfullbufs)

+# (e.g. COSS). Defaults to 0.
+#
+# max-size=n, refers to the max object size this storedir supports.
+# It is used to initially choose the storedir to dump the object.
+# Note: To make optimal use of the max-size limits you should order

+# OPTIONS FOR URL REWRITING
+# -----------------------------------------------------------------------------
+
+# TAG: storeurl_rewrite_program
+# Specify the location of the executable for the Store URL rewriter.
+# The Store URL rewriter allows URLs to be "normalised" ; mapping
+# multiple URLs to a single URL representation for cache operations.
+#
+# For example, if you request an object at:
+#
+# http://srv1.example.com/image.gif
+#
+# and a subsequent request for:
+#
+# http://srv2.example.com/image.gif
+#
+# then Squid will treat these both as different URLs and cache them
+# seperately.
+#
+# This is almost the normal case, but an increasing number of sites
+# distribute the same content between multiple frontend hosts.
+# The Store URL rewriter allows you to rewrite these URLs to one URL
+# to use for cache operations, but not -fetches-. Fetches are still
+# made from the original site, but stored with the store URL rewritten
+# URL as the store key.
+#
+# For each requested URL rewriter will receive on line with the format
+#
+# URL <SP> client_ip "/" fqdn <SP> user <SP> method <SP> urlgroup
+# [<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).
+#
+# By default, a Store URL rewriter is not used.
+#
+# Please note - the normal URL rewriter rewrites Squid's _destination_
+# URL - ie, what it fetches. The Store URL rewriter rewrites Squid's
+# _store_ URL - ie, what it uses to store and retrieve objects.

+# URL with "301:" (moved permanently) or 302: (moved temporarily).
+#
+# It can also return a "urlgroup" that can subsequently be matched
