NAME
squid - proxy caching server
SYNOPSIS
squid [ -dhsvzCDFNRVYX ] [ -f config-file ] [ -[ au ] port ] [ -k signal ]
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 nega-
tive 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 FAQ
included with the distribution and the documentation at the squid home page http://www.squid-cache.org
OPTIONS
-a port
Specify HTTP port number (default: 3128).
-d level
Write debugging to stderr also.
-f file
Use the given config-file instead of /etc/squid/squid.conf
-h Print help message.
-k reconfigure | rotate | shutdown | interrupt | kill | debug | check | parse
Parse configuration file, then send signal to running copy (except -k parse) and exit.
-s Enable logging to syslog.
-u port
Specify ICP port number (default: 3130), disable with 0.
-v Print version.
-z Create swap directories
-C Do not catch fatal signals.
-D Disable initial DNS tests.
-F Don't serve any requests until store is rebuilt.
-N No daemon mode.

-Y Only return UDP_HIT or UDP_MISS_NOFETCH during fast reload.
FILES

tion does not allow access from any browser.
