+# WELCOME TO SQUID 2
+# ------------------
+#
+# 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.
+#
+
+
+# NETWORK OPTIONS
+# -----------------------------------------------------------------------------
+
+# TAG: http_port
+# Usage: port
+# hostname:port
+# 1.2.3.4:port
+#
+# The socket addresses where Squid will listen for HTTP client
+# requests. You may specify multiple socket addresses.
+# There are three forms: port alone, hostname with port, and
+# IP address with port. If you specify a hostname or IP
+# address, then Squid binds the socket to that specific
+# address. This replaces the old 'tcp_incoming_address'
+# option. Most likely, you do not need to bind to a specific
+# address, so you can use the port number alone.
+#
+# The default port number is 3128.
+#
+# If you are running Squid in accelerator mode, then you
+# probably want to listen on port 80 also, or instead.
+#
+# The -a command line option will override the *first* port
+# number listed here. That option will NOT override an IP
+# address, however.
+#
+# You may specify multiple socket addresses on multiple lines.
+#
+#Default:
+# http_port 3128
+
+# TAG: icp_port
+# The port number where Squid sends and receives ICP queries to
+# and from neighbor caches. Default is 3130. To disable use
+# "0". May be overridden with -u on the command line.
+#
+#Default:
+# icp_port 3130
+
+# TAG: htcp_port
+# The port number where Squid sends and receives HTCP queries to
+# and from neighbor caches. Default is 4827. To disable use
+# "0".
+#
+# To enable this option, you must use --enable-htcp with the
+# configure script.
+#
+#Default:
+# htcp_port 4827
+
+# 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
+
+# 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_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 behavior is to not bind to any specific address.
+#
+# A *_incoming_address value of 0.0.0.0 indicates that Squid should
+# listen on all available interfaces.
+#
+# If udp_outgoing_address is set to 255.255.255.255 (the default)
+# then it will use the same socket as udp_incoming_address. Only
+# change this if you want to have ICP queries sent using another
+# address than where this Squid listens for ICP queries from other
+# caches.
+#
+# NOTE, udp_incoming_address and udp_outgoing_address can not
+# have the same value since they both use port 3130.
+#
+# NOTE, tcp_incoming_address has been removed. You can now
+# specify IP addresses on the 'http_port' line.
+#
+#Default:
+# tcp_outgoing_address 255.255.255.255
+# udp_incoming_address 0.0.0.0
+# udp_outgoing_address 255.255.255.255
+
+
+# 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
+#
+# 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
+# connect-timeout=nn
+# digest-url=url
+# allow-miss
+#
+# 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 queries to this address.
+# Only useful when sending to a multicast group.

+# 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

+# 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,

+# * When multiple domains are given for a particular
+# cache-host, the first matched domain is applied.

+#
+# Modifying the neighbor type for specific domains is now

+
+# 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

+#
+# icp_query_timeout 2000
+#
+#Default:
+# icp_query_timeout 0
+
+# 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

+# 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
+
+# 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.
+#

+#
+# '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

+#
+# In-transit objects have priority over the others. When

+#
+# 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

+# The low- and high-water marks for cache object replacement.
+# Replacement begins when the swap (disk) usage is above the

+#
+# 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

+# then.
+#
+# If the transfer has less than 'quick_abort_min' KB remaining,

+
+# 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

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

+#
+#Default:
+# connect_timeout 2 minutes
+
+# TAG: peer_connect_timeout time-units
+# This parameter specifies how long to wait for a pending TCP

+#
+#Default:
+# request_timeout 30 seconds
+
+# TAG: client_lifetime time-units
+# The maximum amount of time that a client (browser) is allowed to

+# 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
+
+# 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: httpd_accel_host
+# TAG: httpd_accel_port
+# If you want to run Squid as an httpd accelerator, define the

+#
+# If you want virtual host support then specify the hostname
+# as "virtual".
+#
+# If you want virtual port support then specify the port as "0".
+#
+# NOTE: enabling httpd_accel_host disables proxy-caching and
+# ICP. If you want these features enabled also, then set

+#Default:
+# httpd_accel_port 80
+
+# TAG: httpd_accel_single_host on|off
+# If you are running Squid as a accelerator and have a single backend
+# server then set this to on. This causes Squid to forward the request

+# says.
+#
+# Leave this at off if you have multiple backend servers, and use a
+# redirector (or host table or private DNS) to map the requests to the
+# appropriate backend servers. Note that the mapping needs to be a
+# 1-1 mapping between requested and backend (from redirector) domain
+# names or caching will fail, as cacing is performed using the
+# URL returned from the redirector.
+#
+# See also redirect_rewrites_host_header.
+#
+#Default:

+
+# TAG: httpd_accel_with_proxy on|off
+# If you want to use Squid as both a local httpd accelerator
+# and as a proxy, change this to 'on'. Note however that your
+# proxy users may have trouble to reach the accelerated domains
+# unless their browsers are configured not to use this proxy for

+#
+#Default:
+# httpd_accel_with_proxy off
+
+# TAG: httpd_accel_uses_host_header on|off
+# HTTP/1.1 requests include a Host: header which is basically the
+# hostname from the URL. Squid can be an accelerator for
+# different HTTP servers by looking at this header. However,
+# Squid does NOT check the value of the Host header, so it opens
+# a big security hole. We recommend that this option remain
+# disabled unless you are sure of what you are doing.
+#
+# However, you will need to enable this option if you run Squid
+# as a transparent proxy. Otherwise, virtual servers which
+# require the Host: header will not be properly cached.

+# 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 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

+# Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys
+#
+# This can be used to return a ERR_ page for requests which

+
+# TAG: memory_pools on|off
+# If set, Squid will keep pools of allocated (but unused) memory

+
+# 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 not set (default) or set to zero, 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:
+# none
+
+# TAG: forwarded_for on|off
+# If set, Squid will include your system's IP address or name

+# TAG: always_direct
+# Usage: always_direct allow|deny [!]aclname ...
+#
+# Here you can use ACL elements to specify requests which should

+# This option replaces some v1.1 options such as inside_firewall
+# and firewall_ip.
+#
+#Default:
+# none
+
+# TAG: anonymize_headers
+# Usage: anonymize_headers allow|deny header_name ...
+#
+# This option replaces the old 'http_anonymizer' option with
+# something that is much more configurable. You may now
+# specify exactly which headers are to be allowed, or which
+# are to be removed from outgoing requests.
+#
+# There are two methods of using this option. You may either
+# allow specific headers (thus denying all others), or you
+# may deny specific headers (thus allowing all others).
+#
+# For example, to achieve the same behavior as the old
+# 'http_anonymizer standard' option, you should use:
+#
+# anonymize_headers deny From Referer Server
+# anonymize_headers deny User-Agent WWW-Authenticate Link
+#
+# Or, to reproduce the old 'http_anonymizer paranoid' feature
+# you should use:

+#
+# When a connection to a host is initiated, and that host has
+# several IP addresses, the default connection timeout is reduced

+# 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

+#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

+#
+#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 RFC2616.
+# 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: broken_posts
+# A list of ACL elements which, if matched, causes Squid to send
+# a extra CRLF pair after the body of a PUT/POST request.
+#
+# Some HTTP servers has broken implementations of PUT/POST,
+# and rely on a extra CRLF pair sent by some WWW clients.
+#
+# Quote from RFC 2068 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.
+#
+#Example:
+# acl buggy_server url_regex ^http://....
+# broken_posts allow buggy_server
+#
+#Default:
+# none
+
+# TAG: mcast_miss_addr
+# Note: This option is only available if Squid is rebuilt with the
+# -DMULTICAST_MISS_STREAM option
+#
+# 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 255.255.255.255
+
+# TAG: mcast_miss_ttl
+# Note: This option is only available if Squid is rebuilt with the
+# -DMULTICAST_MISS_TTL option
+#
+# 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 option
+#
+# 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

+#
+# The URLs that are sent in the multicast miss stream are
+# encrypted. This is the encryption key.
+#
+#Default:
+# mcast_miss_encode_key XXXXXXXXXXXXXXXX
+
+# TAG: nonhierarchical_direct
+# By default, Squid will send any non-hierarchical requests
+# (matching hierarchy_stoplist or not cachable request type) direct
+# to origin servers.
+#
+# If you set this to off, then 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 then 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 by some
+# reason like it to first try going direct and only use a parent if
+# going direct fails then set this to off.
+#
+# 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.
+#
+#Default:
+# prefer_direct off
+
+# 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
+
+# TAG: coredump_dir
+# By default Squid leaves core files in the first cache_dir
+# directory. 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:
+# none
+
+# TAG: redirector_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,
+# then users may have access to pages that they should not
+# be allowed to request.
+#
+#Default:
+# redirector_bypass off
+
+# TAG: ignore_unknown_nameservers
+# By default Squid checks that DNS responses are received
+# from the same IP addresses that 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: digest_generation
+# Note: This option is only available if Squid is rebuilt with the
+# --enable-cache-digests option
+#
+# 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 USE_CACHE_DIGESTS defined.
+#
+#Default:
+# digest_generation on
+
+# TAG: digest_bits_per_entry
+# Note: This option is only available if Squid is rebuilt with the
+# --enable-cache-digests option
+#
+# 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)
+# Note: This option is only available if Squid is rebuilt with the
+# --enable-cache-digests option
+#
+# This is the number of seconds between Cache Digest rebuilds.
+#
+#Default:
+# digest_rebuild_period 1 hour
+
+# TAG: digest_rewrite_period (seconds)
+# Note: This option is only available if Squid is rebuilt with the
+# --enable-cache-digests option
+#
+# This is the number of seconds between Cache Digest writes to
+# disk.
+#
+#Default:
+# digest_rewrite_period 1 hour
+
+# TAG: digest_swapout_chunk_size (bytes)
+# Note: This option is only available if Squid is rebuilt with the
+# --enable-cache-digests option
+#
+# 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)
+# Note: This option is only available if Squid is rebuilt with the
+# --enable-cache-digests option
+#
+# 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
+
+# TAG: chroot
+# Use this to have Squid do a chroot() while initializing. This
+# also causes Squid to fully drop root privileges after
+# initializing. This means, for example, that if you use a HTTP
+# port less than 1024 and try to reconfigure, you will get an
+# error.
+#
+#Default:
+# none
+
+# 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: pipeline_prefetch
+# To boost the performance of pipelined requests to closer
+# match that of a non-proxied environment Squid tries to fetch
+# up to two requests in parallell from a pipeline.
+#
+#Default:
+# pipeline_prefetch on
+
+# TAG: extension_methods
+# Squid only knows about standardized HTTP request methods.
+# You can add up to 20 additional "extension" methods here.
+#
+#Default:
+# none
+
+# 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
+# value, Squid prints a WARNING with debug level 0 to get
+# the administrators attention.
+#
+#Default:
+# high_memory_warning 0
+
+# TAG: store_dir_select_algorithm
+# Set this to 'round-robin' as an alternative.
+#
+#Default:
+# store_dir_select_algorithm least-load
+
+# TAG: forward_log
+# Note: This option is only available if Squid is rebuilt with the
+# -DWIP_FWD_LOG option
+#
+# Logs the server-side requests.
+#
+# This is currently work in progress.
+#
+#Default:
+# none
+
+# TAG: ie_refresh on|off
+# Microsoft Internet Explorer up until version 5.5 Service
+# Pack 1 has an issue with transparent proxies, wherein it
+# is impossible to force a refresh. Turning this on provides
+# a partial fix to the problem, by causing all IMS-REFRESH
+# requests from older IE versions to check the origin server
+# for fresh content. This reduces hit ratio by some amount
+# (~10% in my experience), but allows users to actually get
+# fresh content when they want it. Note that because Squid
+# cannot tell if the user is using 5.5 or 5.5SP1, the behavior
+# of 5.5 is unchanged from old versions of Squid (i.e. a
+# forced refresh is impossible). Newer versions of IE will,
+# hopefully, continue to have the new behavior and will be
+# handled based on that assumption. This option defaults to
+# the old Squid behavior, which is better for hit ratios but
+# worse for clients using IE, if they need to be able to
+# force fresh content.
+#
+#Default:
+# ie_refresh off
