NAME
squid - proxy caching server
SYNOPSIS
squid [ -dhirsvzCDFNRVYX ] [ -l facility ] [ -f config-file ] [ -[ au ]
port ] [ -k signal ] [ -n service-name ] [ -O cmd-line ]
DESCRIPTION
squid is a high-performance proxy caching server for web clients, sup-
porting FTP, gopher, and HTTP data objects. Unlike traditional caching
software, squid handles all requests in a single, non-blocking, I/O-
driven process.
squid keeps meta data and especially hot objects cached in RAM, caches
DNS lookups, supports non-blocking DNS lookups, and implements negative
caching of failed requests.
squid supports SSL, extensive access controls, and full request log-
ging. By using the lightweight Internet Cache Protocol, squid caches
can be arranged in a hierarchy or mesh for additional bandwidth sav-
ings.
squid consists of a main server program squid, a Domain Name System
lookup program dnsserver, some optional programs for rewriting requests
and performing authentication, and some management and client tools.
When squid starts up, it spawns a configurable number of dnsserver pro-
cesses, each of which can perform a single, blocking Domain Name System
(DNS) lookup. This reduces the amount of time the cache waits for DNS
lookups.
squid is derived from the ARPA-funded Harvest Project http://har-
vest.cs.colorado.edu/
This manual page only lists the command line arguments. For details on
how to configure squid see the file /etc/squid/squid.conf, the Squid
FAQ and the documentation at the squid home page http://www.squid-

FILES
/etc/squid/squid.conf
The main configuration file. You must initially make changes to
this file for squid to work. For example, the default configu-
ration does not allow access from any browser.
/etc/squid/squid.conf.default
Reference copy of the configuration file. Always kept up to date
with the version of Squid you are using. Use this to look up
configuration syntax after upgrading.
/etc/squid/mime.conf (mime_table)
MIME type mappings for FTP gatewaying
/usr/share/errors/English (error_directory)
