+# WELCOME TO SQUID 2
+# ------------------
+#
+# This is the default Squid configuration file. You may wish
+# to look at http://cache.is.co.za/squid/ for documentation,
+# or the Squid home page (http://squid.nlanr.net/) for the FAQ.
+#
+
+
+# NETWORK OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: http_port
+# The port number where Squid will listen for HTTP client
+# requests. Default is 3128, for httpd-accel mode use port 80.
+# May be overridden with -a on the command line.
+#
+# You may specify multiple ports here, but they MUST all be on
+# a single line.
+#
+http_port 8080
+
+# TAG: icp_port
+# The port number where Squid sends and receives ICP requests to
+# and from neighbor caches. Default is 3130. To disable use
+# "0". May be overridden with -u on the command line.
+#
+#icp_port 3130
+
+# TAG: htcp_port
+# The port number where Squid sends and receives ICP requests to
+# and from neighbor caches. Default is 4827. To disable use
+# "0".
+#
+#htcp_port 4827
+
+# TAG: mcast_groups
+# This tag specifies a list of multicast groups which your server
+# should join to receive multicasted ICP requests.
+#
+# 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. NLANR has been
+# assigned a block of multicast address space for use in Web
+# Caching. Plese write to us at nlanr-cache@nlanr.net to receive
+# an address for your own use.
+#
+# If you are unsure about multicast, please read the Multicast
+# chapter in the Squid FAQ (http://squid.nlanr.net/Squid/FAQ/).
+#
+# Usage: mcast_groups 239.128.16.128 224.0.1.20
+#
+# By default, Squid doesn't listen on any multicast groups.
+#
+#mcast_groups 239.128.16.128
+
+# TAG: tcp_incoming_address
+# TAG: tcp_outgoing_address
+# TAG: udp_incoming_address
+# TAG: udp_outgoing_address
+# Usage: tcp_incoming_address 10.20.30.40
+# udp_outgoing_address fully.qualified.domain.name
+#
+# tcp_incoming_address is used for the HTTP socket which accepts
+# connections from clients and other caches.
+# tcp_outgoing_address is used for connections made to remote
+# servers and other caches.
+# udp_incoming_address is used for the ICP socket receiving packets
+# from other caches.
+# udp_outgoing_address is used for ICP packets sent out to other
+# caches.
+#
+# The default behaviour is to not bind to any specific address.
+#
+# NOTE, udp_incoming_address and udp_outgoing_address can not
+# have the same value (unless it is 0.0.0.0) since they both use
+# port 3130.
+#
+#tcp_incoming_address 0.0.0.0

+
+# OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM
+# -----------------------------------------------------------------------------
+
+# TAG: cache_peer
+# To specify other caches in a hierarchy, use the format:
+#
+# hostname type http_port icp_port
+#
+# For example,
+#
+# # proxy icp
+# # hostname type port port options
+# # -------------------- -------- ----- ----- -----------
+# cache_peer parent.foo.net parent 3128 3130 [proxy-only]
+# cache_peer sib1.foo.net sibling 3128 3130 [proxy-only]
+# cache_peer sib2.foo.net sibling 3128 3130 [proxy-only]
+#
+# type: either 'parent', 'sibling', or 'multicast'.
+#
+# proxy_port: The port number where the cache listens for proxy
+# requests.
+#
+# icp_port: Used for querying neighbor caches about
+# objects. To have a non-ICP neighbor
+# specify '7' for the ICP port and make sure the
+# neighbor machine has the UDP echo port
+# enabled in its /etc/inetd.conf file.
+#
+# options: proxy-only
+# weight=n
+# ttl=n
+# no-query
+# default
+# round-robin
+# multicast-responder
+# closest-only
+# no-digest
+# no-netdb-exchange
+# no-delay
+# login=user:password
+#
+# use 'proxy-only' to specify that objects fetched
+# from this cache should not be saved locally.
+#
+# use 'weight=n' to specify a weighted parent.
+# The weight must be an integer. The default weight
+# is 1, larger weights are favored more.
+#
+# use 'ttl=n' to specify a IP multicast TTL to use
+# when sending an ICP request 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 below.
+#
+# use 'no-query' to NOT send ICP queries to this
+# neighbor.
+#
+# use 'default' if this is a parent cache which can
+# be used as a "last-resort." You should probably
+# only use 'default' in situations where you cannot
+# use ICP with your parent cache(s).
+#
+# use 'round-robin' to define a set of parents which
+# should be used in a round-robin fashion in the
+# absence of any ICP queries.
+#
+# 'multicast-responder' indicates that 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.
+#
+# use 'no-digest' to NOT request cache digests from
+# this neighbor.
+#
+# 'no-netdb-exchange' disables requesting ICMP
+# RTT database (NetDB) from the neighbor.
+#
+# use 'no-delay' to prevent access to this neighbor
+# from influencing the delay pools.
+#
+# use 'login=user:password' if this is a personal/workgroup
+# proxy and your parent requires proxy authentication.
+#
+# NOTE: non-ICP neighbors must be specified as 'parent'.
+#
+#cache_peer hostname type 3128 3130
+
+# TAG: cache_peer_domain
+# Use to limit the domains for which a neighbor cache will be
+# queried. Usage:
+#
+# cache_peer_domain cache-host domain [domain ...]
+# cache_peer_domain cache-host !domain
+#
+# For example, specifying
+#
+# cache_peer_domain parent.foo.net .edu
+#
+# has the effect such that UDP query packets are sent to
+# 'bigserver' only when the requested object exists on a
+# server in the .edu domain. Prefixing the domainname
+# with '!' means that the cache will be queried for objects
+# NOT in that domain.
+#
+# NOTE: * Any number of domains may be given for a cache-host,
+# either on the same or separate lines.
+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.
+# * Cache hosts with no domain restrictions are queried
+# for all requests.
+# * There are no defaults.
+# * There is also a 'cache_peer_access' tag in the ACL
+# section.
+
+# TAG: neighbor_type_domain
+# usage: neighbor_type_domain parent|sibling domain domain ...
+#
+# Modifying the neighbor type for specific domains is now
+# 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 parent cache.foo.org 3128 3130
+# neighbor_type_domain cache.foo.org sibling .com .net
+# neighbor_type_domain cache.foo.org sibling .au .de
+
+# 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
+#
+#icp_query_timeout 0
+
+# 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.
+#
+#mcast_icp_query_timeout 2000
+
+# 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.
+#
+#dead_peer_timeout 10 seconds
+
+# TAG: hierarchy_stoplist
+# A list of words which, if found in a URL, cause the object to
+# be handled directly by this cache. In other words, use this
+# to not query neighbor caches for certain objects. You may
+# list this option multiple times.
+#
+# The default is to directly fetch URLs containing 'cgi-bin' or '?'.
+#
+#hierarchy_stoplist cgi-bin ?
+
+# TAG: no_cache
+# A list of ACL elements which, if matched, cause the reply to
+# immediately removed from the cache. In other words, use this
+# to force certain objects to never be cached.
+#
+# You must use the word 'DENY' to indicate the ACL names which should
+# NOT be cached.
+#
+# There is no default. We recommend you uncomment the following
+# two lines.
+#
+#acl QUERY urlpath_regex cgi-bin \?
+#no_cache deny QUERY
+
+
+# OPTIONS WHICH AFFECT THE CACHE SIZE
+# -----------------------------------------------------------------------------
+
+# TAG: cache_mem (bytes)
+# NOTE: THIS PARAMETER DOES NOT SPECIFY THE MAXIMUM PROCESS
+# SIZE. IT PLACES A LIMIT ON ONE ASPECT OF SQUID'S MEMORY
+# USAGE. SQUID USES MEMORY FOR OTHER THINGS AS WELL.
+# YOUR PROCESS WILL PROBABLY BECOME TWICE OR THREE TIMES
+# BIGGER THAN THE VALUE YOU PUT HERE
+#
+# '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.
+#
+# The values of cache_mem_low and cache_mem_high (below) can be
+# used to tune the use of the memory pool. When the high mark is
+# reached, in-transit and hot objects will be released to clear
+# space. When an object transfer is completed, it will remain in
+# memory only if the current memory usage is below the low water
+# mark.
+#
+# The default is 8 Megabytes.
+#
+cache_mem 8 MB
+
+# TAG: cache_swap_low (percent, 0-100)
+# TAG: cache_swap_high (percent, 0-100)
+# The low- and high-water marks for cache LRU replacement. LRU
+# replacement begins when the high-water mark is reached and ends
+# when enough objects have been removed and the low-water mark is
+# reached. 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.
+#
+cache_swap_low 90
+cache_swap_high 95
+
+# TAG: cache_mem_low (in percent, 0-100)
+# TAG: cache_mem_high (in percent, 0-100)
+# The low- and high-water mark for cache memory storage. When
+# the amount of RAM used by the hot-object RAM cache reaches this
+# point, the cache starts throwing objects out of the RAM cache
+# (but they remain on disk). Defaults are 75% and 90%.
+#
+cache_mem_low 75
+cache_mem_high 90
+
+# TAG: maximum_object_size (bytes)
+# Objects larger than this size will NOT be saved on disk. The
+# value is specified in kilobytes, and the default is 4MB. 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 speed more than your want to
+# save bandwidth you should leave this low.
+#
+maximum_object_size 4096 KB
+
+# TAG: ipcache_size (number of entries)

+# LOGFILE PATHNAMES AND CACHE DIRECTORIES
+# -----------------------------------------------------------------------------
+
+# TAG: cache_dir
+# Usage:
+#
+# cache_dir Directory-Name Mbytes Level-1 Level2
+#
+# You can specify multiple cache_dir lines to spread the
+# cache among different disk partitions.
+#
+# 'Directory' is a top-level directory where cache swap
+# files will be stored. If you want to use an entire disk
+# for caching, then this can be the mount-point directory.
+# The directory must exist and be writable by the Squid

+#
+# If no 'cache_dir' lines are specified, the following
+# default will be used: /usr/cache.
+#
+# 'Mbytes' is the amount of disk space (MB) to use under this

+# configuration.
+#
+# '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

+#
+cache_store_log /var/log/squid/store.log
+
+# TAG: cache_swap_log
+# Location for the cache "swap.log." This log file holds the

+# cache during startup. Normally this file resides in the first
+# '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!
+#
+#cache_swap_log
+
+# TAG: emulate_httpd_log on|off
+# The Cache can emulate the log file format which many 'httpd'

+#
+#log_mime_hdrs off
+
+# TAG: useragent_log

+#
+pid_filename /var/run/squid.pid
+
+# 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".
+#

+#
+#ident_lookup off
+
+# TAG: log_fqdn on|off
+# Turn this on if you wish to log fully qualified domain names

+
+# 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
+# resonable for your domain, like wwwuser@somewhere.net
+#
+# The reason why this is domainless by default is that the

+# description of Squid's refresh algorithm. Basically a
+# cached object is: (the order is changed from 1.1.X)
+#
+# STALE if age > max
+# FRESH if expires < now, else STALE
+# FRESH if lm-factor < percent, else STALE
+# FRESH if age < min
+# else STALE
+#
+# The refresh_pattern lines are checked in the order listed here.
+# The first entry which matches is used. If none of the entries
+# match, then the default will be used.
+#
+#Default:
+#refresh_pattern . 0 20% 4320
+
+# TAG: reference_age
+# As a part of normal operation, Squid performs Least Recently
+# Used removal of cached objects. The LRU age for removal is
+# computed dynamically, based on the amount of disk space in
+# use. The dynamic value can be seen in the Cache Manager 'info'
+# output.
+#
+# The 'reference_age' parameter defines the maximum LRU age. For
+# example, setting reference_age to '1 week' will cause objects
+# to be removed if they have not been accessed for a week or
+# more. The default value is one month.
+#
+# Specify a number here, followed by units of time. For example:
+# 1 week
+# 3.5 days
+# 4 months
+# 2.2 hours
+#
+#reference_age 1 month
+
+# TAG: quick_abort_min (KB)
+# TAG: quick_abort_max (KB)
+# TAG: quick_abort_pct (percent)
+# The cache can be configured to continue downloading aborted
+# requests. 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. Setting 'quick_abort_min' to -1
+# will disable the quick_abort feature.
+#
+# 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.

+# TAG: negative_ttl time-units
+# Time-to-Live (TTL) for failed requests. Certain types of

+#negative_ttl 5 minutes
+
+# TAG: positive_dns_ttl time-units

+
+# 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 then 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 -1 causes Squid to always fetch the object from the
+# beginning so that it may cache the result. (2.0 style)
+#
+# A value of 0 causes Squid to never fetch more than the client
+# client requested. (default)

+# TIMEOUTS
+# -----------------------------------------------------------------------------
+
+# TAG: connect_timeout time-units
+# Some systems (notably Linux) can not be relied upon to properly

+#
+#request_timeout 30 seconds
+
+# TAG: client_lifetime time-units
+# The maximum amount of time that a client (browser) is allowed to
+# remain connected to the cache process. This protects the Cache
+# from having alot 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,

+
+# TAG: half_closed_clients
+# Some clients may shutdown the sending side of their TCP
+# connections, while leaving their receiving sides open. Sometimes,
+# Squid can not tell the difference between a half-closed and a
+# fully-closed TCP connection. By default, half-closed client
+# connections are kept open until a read(2) or write(2) on the
+# socket returns an error. Change this option to 'off' and Squid
+# will immediately close client connections when read(2) returns
+# "no more data to read."

+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should
+# ALWAYS be forwarded directly to origin servers. For example,
+# to always directly forward requests for local servers 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
+#
+# This option replaces some v1.1 options such as local_domain
+# and local_ip.
+
+# 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
+# acl all src 0.0.0.0/0.0.0.0
+# never_direct deny local-servers
+# never_direct allow all
+#
+# or if squid is inside a firewall and there is local intranet
+# servers inside the firewall then 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 option replaces some v1.1 options such as inside_firewall
+# and firewall_ip.
+
+# TAG: fake_user_agent
+# If you use the paranoid http_anonymizer setting, Squid will strip
+# your User-agent string from the request. Some Web servers will
+# refuse your request without a User-agent string. Use this to
+# fake one up. For example:
+#
+# fake_user_agent Nutscrape/1.0 (CP/M; 8-bit)
+# (credit to Paul Southworth pauls@etext.org for this one!)

+
+# TAG: minimum_retry_timeout (seconds)
+# This specifies the minimum connect timeout, for when the
+# connect timeout is reduced to compensate for the availability
+# of multiple IP addresses.
+#
+# When a connection to a host is initiated, and that host has
+# several IP addresses, the default connection timeout is reduced
+# by dividing it by the number of addresses. So, a site with 15
+# addresses would then have a timeout of 8 seconds for each
+# address attempted. To avoid having the timeout reduced to the
+# point where even a working host would not have a chance to
+# respond, this setting is provided. The default, and the
+# minimum value, is five seconds, and the maximum value is sixty
+# seconds, or half of connect_timeout, whichever is greater and
+# less than connect_timeout.
+#
+#minimum_retry_timeout 5 seconds
+
+# TAG: maximum_single_addr_tries
+# This sets the maximum number of connection attempts for a
+# host that only has one address (for multiple-address hosts,
+# each address is tried once).
+#
+# The default value is three tries, the (not recommended)
+# maximum is 255 tries. A warning message will be generated
+# if it is set to a value greater than ten.

+# TAG: forward_snmpd_port

+# snmp port (usually 161). We do not use getservbyname() to
+# allow you to set Squid into port 161 and your system's snmpd to
+# another port by changing /etc/services.

+# -----------------------------------------------------------------------------
+#
+# A general note on delay pools - the first matched delay pool is used,
