# Squid normally listens to port 3128
http_port 3128

	Usage:	port [options]
		hostname:port [options]
		1.2.3.4:port [options]

	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, 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.

	If you are running Squid in accelerator mode, you
	probably want to listen on port 80 also, or instead.

	The -I command line option will override the *first* port
	specified here.

	You may specify multiple socket addresses on multiple lines.

	Options:

	   transparent	Support for transparent interception of
			outgoing requests without browser settings.

	   tproxy	Support Linux TPROXY for spoofing outgoing
			connections using the client IP address.

	   accel	Accelerator mode. See also the related vhost,
			vport and defaultsite directives.

	   defaultsite=domainname
			What to use for the Host: header if it is not present
			in a request. Determines what site (not origin server)
			accelerators should consider the default.
			Defaults to visible_hostname:port if not set
			May be combined with vport=NN to override the port number.
			Implies accel.

	   vhost	Accelerator mode using Host header for virtual
			domain support. Implies accel.

	   vport	Accelerator with IP based virtual host support.
			Implies accel.

	   vport=NN	As above, but uses specified port number rather
			than the http_port number. Implies accel.

	   allow-direct	Allow direct forwarding in accelerator mode. Normally
	   		accelerated requests is denied direct forwarding as it
			never_direct was used.

	   urlgroup=	Default urlgroup to mark requests with (see
			also acl urlgroup and url_rewrite_program)

	   protocol=	Protocol to reconstruct accelerated requests with.
			Defaults to http.

	   no-connection-auth
			Prevent forwarding of Microsoft connection oriented
			authentication (NTLM, Negotiate and Kerberos)

	   act-as-origin
	   		Act is if this Squid is the origin server.
			This currently means generate own Date: and
			Expires: headers. Implies accel.

	   http11	Enables HTTP/1.1 support to clients. The HTTP/1.1
			support is still incomplete with an internal HTTP/1.0
			hop, but should work with most clients. The main
			HTTP/1.1 features missing due to this is forwarding
			of requests using chunked transfer encoding (results
			in 411) and forwarding of 1xx responses (silently
			dropped)

	   name=	Specifies a internal name for the port. Defaults to
			the port specification (port or addr:port)

	   tcpkeepalive[=idle,interval,timeout]
			Enable TCP keepalive probes of idle connections
			idle is the initial time before TCP starts probing
			the connection, interval how often to probe, and
			timeout the time before giving up.

	If you run Squid on a dual-homed machine with an internal
	and an external interface we recommend you to specify the
	internal address:port in http_port. This way Squid will only be
	visible on the internal address.
