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. -#	Ports flagged 'transparent', 'intercept', or 'tproxy' have -#	authentication disabled. -# -#	=== Parameters common to all schemes. === -# -#	"program" cmdline -#		Specifies the command for the external authenticator. -# -#		By default, each authentication scheme is not used unless a -#		program is specified. -# -#		See http://wiki.squid-cache.org/Features/AddonHelpers for -#		more details on helper operations and creating your own. -# -#	"key_extras" format -#		Specifies a string to be append to request line format for -#		the authentication helper. "Quoted" format values may contain -#		spaces and logformat %macros. In theory, any logformat %macro -#		can be used. In practice, a %macro expands as a dash (-) if -#		the helper request is sent before the required macro -#		information is available to Squid. -# -#		By default, Squid uses request formats provided in -#		scheme-specific examples below (search for %credentials). -# -#		The expanded key_extras value is added to the Squid credentials -#		cache and, hence, will affect authentication. It can be used to -#		autenticate different users with identical user names (e.g., -#		when user authentication depends on http_port). -# -#		Avoid adding frequently changing information to key_extras. For -#		example, if you add user source IP, and it changes frequently -#		in your environment, then max_user_ip ACL is going to treat -#		every user+IP combination as a unique "user", breaking the ACL -#		and wasting a lot of memory on those user records. It will also -#		force users to authenticate from scratch whenever their IP -#		changes. -# -#	"realm" string -#		Specifies the protection scope (aka realm name) which is to be -#		reported to the client for the authentication scheme. It is -#		commonly part of the text the user will see when prompted for -#		their username and password. -# -#		For Basic the default is "Squid proxy-caching web server". -#		For Digest there is no default, this parameter is mandatory. -#		For NTLM and Negotiate this parameter is ignored. -# -#	"children" numberofchildren [startup=N] [idle=N] [concurrency=N] -# -#		The maximum 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 -#		password verifications are done via a (slow) network you are -#		likely to need lots of authenticator processes. -# -#		The startup= and idle= options permit some skew in the exact -#		amount run. A minimum of startup=N will begin during startup -#		and reconfigure. Squid will start more in groups of up to -#		idle=N in an attempt to meet traffic needs and to keep idle=N -#		free above those traffic needs up to the maximum. -# -#		The concurrency= option sets the number of concurrent requests -#		the helper can process.  The default of 0 is used for helpers -#		who only supports one request at a time. Setting this to a -#		number greater than 0 changes the protocol used to include a -#		channel ID field first on the request/response line, allowing -#		multiple requests to be sent to the same helper in parallel -#		without waiting for the response. -# -#		Concurrency must not be set unless it's known the helper -#		supports the input format with channel-ID fields. -# -#		NOTE: NTLM and Negotiate schemes do not support concurrency -#			in the Squid code module even though some helpers can. -# -# -# -#	=== Example Configuration === -# -#	This configuration displays the recommended authentication scheme -#	order from most to least secure with recommended minimum configuration -#	settings for each scheme: -# -##auth_param negotiate program <uncomment and complete this line to activate> -##auth_param negotiate children 20 startup=0 idle=1 -##auth_param negotiate keep_alive on -## -##auth_param digest program <uncomment and complete this line to activate> -##auth_param digest children 20 startup=0 idle=1 -##auth_param digest realm Squid proxy-caching web server -##auth_param digest nonce_garbage_interval 5 minutes -##auth_param digest nonce_max_duration 30 minutes -##auth_param digest nonce_max_count 50 -## -##auth_param ntlm program <uncomment and complete this line to activate> -##auth_param ntlm children 20 startup=0 idle=1 -##auth_param ntlm keep_alive on -## -##auth_param basic program <uncomment and complete this line> -##auth_param basic children 5 startup=5 idle=1 -##auth_param basic realm Squid proxy-caching web server -##auth_param basic credentialsttl 2 hours -#Default: -# none - -#  TAG: authenticate_cache_garbage_interval -#	The time period between garbage collection across the username cache. -#	This is a trade-off between memory utilization (long intervals - say -#	2 days) and CPU (short intervals - say 1 minute).

Standby connection failures -#			count towards this limit. 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. Excessive use -#			of this option may result in forwarding loops. One way -#			to prevent peering loops when using this option, is to -#			deny cache peer usage on requests from a peer: -#			acl fromPeer ... -#			cache_peer_access peerName deny fromPeer -#	 -#	max-conn=N 	Limit the number of concurrent connections the Squid -#			may open to this peer, including already opened idle -#			and standby connections. There is no peer-specific -#			connection limit by default. -#	 -#			A peer exceeding the limit is not used for new -#			requests unless a standby connection is available. -#	 -#			max-conn currently works poorly with idle persistent -#			connections: When a peer reaches its max-conn limit, -#			and there are idle persistent connections to the peer, -#			the peer may not be selected because the limiting code -#			does not know whether Squid can reuse those idle -#			connections. -#	 -#	standby=N	Maintain a pool of N "hot standby" connections to an -#			UP peer, available for requests when no idle -#			persistent connection is available (or safe) to use. -#			By default and with zero N, no such pool is maintained. -#			N must not exceed the max-conn limit (if any). -#	 -#			At start or after reconfiguration, Squid opens new TCP -#			standby connections until there are N connections -#			available and then replenishes the standby pool as -#			opened connections are used up for requests. A used -#			connection never goes back to the standby pool, but -#			may go to the regular idle persistent connection pool -#			shared by all peers and origin servers. -#	 -#			Squid never opens multiple new standby connections -#			concurrently.  This one-at-a-time approach minimizes -#			flooding-like effect on peers. Furthermore, just a few -#			standby connections should be sufficient in most cases -#			to supply most new requests with a ready-to-use -#			connection. -#	 -#			Standby connections obey server_idle_pconn_timeout. -#			For the feature to work as intended, the peer must be -#			configured to accept and keep them open longer than -#			the idle timeout at the connecting Squid, to minimize -#			race conditions typical to idle used persistent -#			connections. Default request_timeout and -#			server_idle_pconn_timeout values ensure such a -#			configuration. -#	 -#	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 identify 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. -#			This overrides the spoof_client_ip ACL. -#	 -#	proxy-only	objects fetched from the peer will not be stored locally. -#	 -#Default: -# none - -#  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 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. -#Default: -# none - -#  TAG: cache_peer_access -#	Restricts usage of cache_peer proxies. -# -#	Usage: -#		cache_peer_access peer-name allow|deny [!]aclname ... -# -#	For the required peer-name parameter, use either the value of the -#	cache_peer name=value parameter or, if name=value is missing, the -#	cache_peer hostname parameter. -# -#	This directive narrows down the selection of peering candidates, but -#	does not determine the order in which the selected candidates are -#	contacted. That order is determined by the peer selection algorithms -#	(see PEER SELECTION sections in the cache_peer documentation). -# -#	If a deny rule matches, the corresponding peer will not be contacted -#	for the current transaction -- Squid will not send ICP queries and -#	will not forward HTTP requests to that peer. An allow match leaves -#	the corresponding peer in the selection. The first match for a given -#	peer wins for that peer. -# -#	The relative order of cache_peer_access directives for the same peer -#	matters. The relative order of any two cache_peer_access directives -#	for different peers does not matter. To ease interpretation, it is a -#	good idea to group cache_peer_access directives for the same peer -#	together. -# -#	A single cache_peer_access directive may be evaluated multiple times -#	for a given transaction because individual peer selection algorithms -#	may check it independently from each other. These redundant checks -#	may be optimized away in future Squid versions. -# -#	This clause only supports fast acl types. -#	See http://wiki.squid-cache.org/SquidFaq/SquidAcl for details. -#Default: -# No peer usage restrictions. - -#  TAG: neighbor_type_domain -#	Modify the cache_peer neighbor type when passing requests -#	about specific domains to the peer. -# -#	Usage: -#		 neighbor_type_domain neighbor parent|sibling domain domain ... -# -#	For example: -#		cache_peer foo.example.com parent 3128 3130 -#		neighbor_type_domain foo.example.com sibling .au .de -# -#	The above configuration treats all requests to foo.example.com as a -#	parent proxy unless the request is for a .au or .de ccTLD domain name. -#Default: -# The peer type from cache_peer directive is used for all requests to that peer. - -#  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 - -#  TAG: forward_max_tries -#	Controls how many different forward paths Squid will try -#	before giving up.

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.

All cached -#	entries are stored in a "database" file, using fixed-size slots. -#	A single entry occupies one or more slots. -# -#	If possible, Squid using Rock Store creates a dedicated kid -#	process called "disker" to avoid blocking Squid worker(s) on disk -#	I/O. One disker kid is created for each rock cache_dir.  Diskers -#	are created only when Squid, running in daemon mode, has support -#	for the IpcIo disk I/O module. -# -#	swap-timeout=msec: Squid will not start writing a miss to or -#	reading a hit from disk if it estimates that the swap operation -#	will take more than the specified number of milliseconds. By -#	default and when set to zero, disables the disk I/O time limit -#	enforcement. Ignored when using blocking I/O module because -#	blocking synchronous I/O does not allow Squid to estimate the -#	expected swap wait time. -# -#	max-swap-rate=swaps/sec: Artificially limits disk access using -#	the specified I/O rate limit. Swap out requests that -#	would cause the average I/O rate to exceed the limit are -#	delayed. Individual swap in requests (i.e., hits or reads) are -#	not delayed, but they do contribute to measured swap rate and -#	since they are placed in the same FIFO queue as swap out -#	requests, they may wait longer if max-swap-rate is smaller. -#	This is necessary on file systems that buffer "too -#	many" writes and then start blocking Squid and other processes -#	while committing those writes to disk.  Usually used together -#	with swap-timeout to avoid excessive delays and queue overflows -#	when disk demand exceeds available disk "bandwidth". By default -#	and when set to zero, disables the disk I/O rate limit -#	enforcement. Currently supported by IpcIo module only. -# -#	slot-size=bytes: The size of a database "record" used for -#	storing cached responses. A cached response occupies at least -#	one slot and all database I/O is done using individual slots so -#	increasing this parameter leads to more disk space waste while -#	decreasing it leads to more disk I/O overheads. Should be a -#	multiple of your operating system I/O page size. Defaults to -#	16KBytes. A housekeeping header is stored with each slot and -#	smaller slot-sizes will be rejected. The header is smaller than -#	100 bytes. -# -# -#	==== COMMON OPTIONS ==== -# -#	no-store	no new objects should be stored to this cache_dir. -# -#	min-size=n	the minimum object size in bytes this cache_dir -#			will accept.

As such they can affect -#	the selection algorithm by limiting the set of considered -#	cache_dir. -# -#	Algorithms: -# -#		least-load -# -#	This algorithm is suited to caches with similar cache_dir -#	sizes and disk speeds. -# -#	The disk with the least I/O pending is selected. -#	When there are multiple disks with the same I/O load ranking -#	the cache_dir with most available capacity is selected. -# -#	When a mix of cache_dir sizes are configured the faster disks -#	have a naturally lower I/O loading and larger disks have more -#	capacity. So space used to store objects and data throughput -#	may be very unbalanced towards larger disks. -# -# -#		round-robin -# -#	This algorithm is suited to caches with unequal cache_dir -#	disk sizes. -# -#	Each cache_dir is selected in a rotation. The next suitable -#	cache_dir is used. -# -#	Available cache_dir capacity is only considered in relation -#	to whether the object will fit and meets the min-size and -#	max-size parameters. -# -#	Disk I/O loading is only considered to prevent overload on slow -#	disks.

The connect_retries attempts must all still -#	complete within the connection timeout period. -# -#	The default is not to re-try if the first connection attempt fails. -#	The (not recommended) maximum is 10 tries. -# -#	A warning message will be generated if it is set to a too-high -#	value and the configured value will be over-ridden. -# -#	Note: These re-tries are in addition to forward_max_tries -#	which limit how many different addresses may be tried to find -#	a useful server. -#Default: -# Do not retry failed connections. - -#  TAG: retry_on_error -#	If set to ON Squid will automatically retry requests when -#	receiving an error response with status 403 (Forbidden), -#	500 (Internal Error), 501 or 503 (Service not available). -#	Status 502 and 504 (Gateway errors) are always retried. -#	 -#	This is mainly useful if you are in a complex cache hierarchy to -#	work around access control errors. -#	 -#	NOTE: This retry will attempt to find another working destination. -#	Which is different from the server which just failed. -#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 - -#  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 and RFC3986 -#		for tolerant handling of generic URI. -#		NOTE: This is one difference between generic URI and HTTP URLs. -# -#	deny:   The request is denied.  The user receives an "Invalid -#		Request" message. -#		This is the behaviour recommended by RFC2616 for safe -#		handling of HTTP request URL. -# -#	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. -#		Note this may be considered a violation of RFC2616 -#		request parsing where whitespace is prohibited in the -#		URL field. -# -#	encode:	The request is allowed and the whitespace characters are -#		encoded according to RFC1738. -# -#	chop:	The request is allowed and the URI is chopped at the -#		first whitespace. -# -# -#	NOTE the current Squid implementation of encode and chop violates -#	RFC2616 by not using a 301 redirect after altering the URL. -#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: balance_on_multiple_ip -#	Modern IP resolvers in squid sort lookup results by preferred access. -#	By default squid will use these IP in order and only rotates to -#	the next listed when the most preffered fails. -# -#	Some load balancing servers based on round robin DNS have been -#	found not to preserve user session state across requests -#	to different IP addresses. -# -#	Enabling this directive Squid rotates IP's per request. -#Default: -# balance_on_multiple_ip off - -#  TAG: pipeline_prefetch -#	HTTP clients may send a pipeline of 1+N requests to Squid using a -#	single connection, without waiting for Squid to respond to the first -#	of those requests. This option limits the number of concurrent -#	requests Squid will try to handle in parallel. If set to N, Squid -#	will try to receive and process up to 1+N requests on the same -#	connection concurrently. -# -#	Defaults to 0 (off) for bandwidth management and access logging -#	reasons. -# -#	NOTE: pipelining requires persistent connections to clients. -# -#	WARNING: pipelining breaks NTLM and Negotiate/Kerberos authentication. -#Default: -# Do not pre-parse pipelined requests. - -#  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: -# disabled. - -#  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: -# disabled. - -#  TAG: high_memory_warning -# Note: This option is only available if Squid is rebuilt with the -#       GNU Malloc with mstats() -# -#	If the memory usage (as determined by gnumalloc, if available and used) -#	exceeds	this amount, Squid prints a WARNING with debug level 0 to get -#	the administrators attention. -#Default: -# disabled. - -#  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 -# Note: This option is only available if Squid is rebuilt with the -#       MS Windows -# -#	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 -#	Reduce the maximum number of filedescriptors supported below -#	the usual operating system defaults. -# -#	Remove from squid.conf to inherit the current ulimit setting. -# -#	Note: Changing this requires a restart of Squid.
