NAME
squid - proxy caching server
SYNOPSIS
squid [ -dhirsvzCDFINRVYX ] [ -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,
supporting 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
logging. By using the lightweight Internet Cache Protocol, squid
caches can be arranged in a hierarchy or mesh for additional bandwidth
savings.
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
processes, 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://harvest.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-

parse
Parse configuration file, then send signal to running copy
(except -k parse) and exit.
-n name
Specify Windows Service name to use for service operations,
default is: Squid

-Y Only return UDP_HIT or UDP_MISS_NOFETCH during fast reload.
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
configuration does not allow access from any browser.
/usr/share/doc/squid/examples/squid.conf
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.
/usr/share/squid/mime.conf (mime_table)
MIME type mappings for FTP gatewaying
/usr/share/squid/errors/en (error_directory)
Error page templates
