NAME

       squid - proxy caching server

SYNOPSIS

       squid [ -dhisrvzCFNRSVYX ] [ -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, ICAP, ICP, HTCP and HTTP data objects.  Unlike
       traditional caching software, squid handles all requests in a single, non-blocking 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 Protocols ICP, HTCP or
       CARP, squid caches can be arranged in a hierarchy or mesh for additional bandwidth savings.

       squid consists of a main server program squid, some optional programs for custom processing and authentication,	and  some  management  and
       client tools.  When squid starts up, it spawns a configurable number of helper processes, each of which can perform parallel lookups.  This
       reduces the amount of time the cache waits for results.

       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  @DEFAULT_CONFIG_FILE@.docu-
       mented,	the  Squid  wiki  FAQ  and  examples  at  http://wiki.squid-cache.org/	,  or  the  configuration  manual  on  the squid home page
       http://www.squid-cache.org/Doc/config/

OPTIONS

       -a port
	      Specify HTTP port number where Squid should listen for requests, in addition to any http_port specifications in squid.conf.

       -d level
	      Write debugging to stderr also.

       -f file
	      Use the given config-file instead of @DEFAULT_CONFIG_FILE@.  If the file name starts with a ! or | then  it  is  assumed	to  be	an
	      external	command  or  command  line.  Can for example be used to pre-process the configuration before it is being read by Squid. To
	      facilitate this Squid also understands the common #line notion to indicate the real source file.

       -h     Print help message.

       -i     Install as a Windows Service (see -n option).

       -k reconfigure | rotate | shutdown | interrupt | kill | debug | check | 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

       -r     Remove a Windows Service (see -n option).

       -s     Enable logging to syslog. Also configurable in @DEFAULT_CONFIG_FILE@

       -l facility
	      Use specified syslog facility. implies -s

       -u port
	      Specify ICP port number (default: 3130), disable with 0.

       -v     Print version and build details.

       -z     Create swap directories

       -C     Do not catch fatal signals.

       -F     Don't serve any requests until store is rebuilt.

       -N     No daemon mode.

       -O options
	      Set Windows Service Command line options in Registry.

       -R     Do not set REUSEADDR on port.

       -S     Double-check swap during rebuild.

       -X     Force full debugging.

       -Y     Only return UDP_HIT or UDP_MISS_NOFETCH during fast reload.

FILES

       @DEFAULT_CONFIG_FILE@
	      The main configuration file.  You must initially make changes to this file for squid to work.  For example, the  default	configura-
	      tion does not allow access from any browser.

       *.default files
	      Reference  copy  of  the configuration file. Always kept up to date with the version of Squid you are using. Use this to look up the
	      default configuration settings and syntax after upgrading.

       @DEFAULT_CONFIG_FILE@.documented
	      Reference copy of the configuration file. Always kept up to date with the version of Squid you are using. Use this to read the docu-
	      mentation  for  configuration options available in your build of Squid. The online configuration manual is also available for a full
	      reference of options.  seehttp://www.squid-cache.org/Doc/config/

       cachemgr.conf
	      The main configuration file for the web cachemgr.cgi tools.

       msntauth.conf
	      The main configuration file for the Sample MSNT authenticator.

       errorpage.css
	      CSS Stylesheet to control the display of generated error pages.  Use this to set any company branding you need,  it  will  apply	to
	      every Language Squid provides error pages for.

       @DEFAULT_MIME_TABLE@ (mime_table)
	      MIME type mappings for FTP gatewaying

       @DEFAULT_ERROR_DIR@
	      Location of squid error pages and templates.
