NAME: mcast_groups
TYPE: wordlist
LOC: Config.mcast_group_list

DOC_START
	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.

	Usage: mcast_groups 239.128.16.128 224.0.1.20

	By default, squid doesn't listen on any multicast groups.

 OPTIONS WHICH AFFECT THE NEIGHBOR SELECTION ALGORITHM

COMMENT_END

NAME: cache_peer
TYPE: peer
DEFAULT: none
LOC: Config.peers
DOC_START
	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 bigserver.usc.edu    parent    3128  3130  [proxy-only]
	cache_peer littleguy1.usc.edu   sibling   3128  3130  [proxy-only]
	cache_peer littleguy1.usc.edu   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

		     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.

	NOTE: non-ICP neighbors must be specified as 'parent'.

NAME: cache_host_domain
TYPE: hostdomain
DEFAULT: none
LOC: none
DOC_START
	Use to limit the domains for which a neighbor cache will be queried.
	Usage:

	cache_host_domain cache-host domain [domain ...]
	cache_host_domain cache-host !domain

	For example, specifying

		cache_host_domain bigserver.usc.edu	.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_host_acl' tag in the ACL
		  section.

	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:

NAME: single_parent_bypass
COMMENT: on|off
TYPE: onoff
DEFAULT: off
LOC: Config.onoff.single_parent_bypass
DOC_START
	This tag specifies that it is okay to bypass the hierarchy
	"Pinging" when there is only a single parent for a given URL.

	Usage: single_parent_bypass on|off

	Before actually sending ICP "ping" packets to parents and
	neighbors, we figure out which hosts would be pinged based
	on the cache_host_domain rules, etc.  Often it may be the
	case that only a single parent cache would be pinged.

	Since there is only a single parent, there is a very good
	chance that we will end up fetching the object from that
	parent.  For this reason, it may be beneficial to avoid
	the ping and just fetch the object anyway.

	However, if we avoid the ping, we will be assuming that the
	parent host is reachable and that the cache process is running.
	By using the ping, we can be reasonably sure that the parent
	host will be able to handle our request.  If the ping fails then
	it may be possible to fetch the object directly from the source.

	To favor the resiliency provided by the ping algorithm,
	single_parent_bypass is 'off' by default.

NAME: source_ping
COMMENT: on|off
TYPE: onoff
DEFAULT: off
LOC: Config.onoff.source_ping
DOC_START
	If source_ping is enabled, then squid will include the source
	provider site in its selection algorithm.  This is accomplished
	by sending ICP "HIT" packets to the UDP echo port of the source
	host.  Note that using source_ping may send a fair amount of UDP
	traffic out on the Internet and may irritate paranoid network
	administrators.

	Note that source_ping is incompatible with inside_firewall.
	For hosts beyond the firewall, source_ping packets will never
	be sent.

	By default, source_ping is off.

	The value of cache_mem is an upper limit on the size of the
	"in-memory object data" pool.  This is a pool of 4k pages used
	to hold object data.

	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.

	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

	By default the cache continues to retrieve objects from
	aborted requests.  This may be undesirable on slow (e.g. SLIP)
	links and/or very busy caches.  Impatient users may tie up
	file descriptors by repeatedly aborting and re-requesting
	non-cachable objects.

	Usage: quick_abort    min-kbytes percent max-kbytes

	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 'min-kbytes' remaining, it
	will finish the retrieval.  Setting minlength to -1 will
	disable the quick_abort feature.

	If the transfer has more than 'max-kbytes' remaining, it
	will abort the retrieval.

	If more than 'percent' of the transfer has completed, it will

	The maximum amount of time that a client (browser) is allowed to

	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

NAME: minimum_retry_timeout
COMMENT: (seconds)
TYPE: time_t
LOC: Config.retry.timeout
DEFAULT: 5 seconds
DOC_START
	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.

	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.

	This configures whether we should be forwarding SNMP requests

	into squid was to enable access to the system's installed
	snmpd with minimal changes.
	This option is turned off by default, check with your /etc/services
	for your system's 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.

        WARNING: Because of squid acting as a proxy snmpd for system
