DESCRIPTION
squidclient is a tool providing a command line interface for retrieving URLs. Designed for testing any HTTP 0.9, 1.0, or 1.1 web server or proxy. This tool can be combined with scripts to perform any basic HTTP operation. Some additional features for access to the squid proxy object cache and management information are provided.

OPTIONS

-a  Do NOT include Accept: header.

-A 'string'
    Send string as User-Agent: header. To omit the header completely set string to empty ('').

-h | --host host

-j hosthdr

-k  Keep the connection active. Default is to do only one request then close.

-l | --local host
    Specify a local IP address to bind to. Default is none.

-m method
    Request method, default is GET. Squid also supports a non-standard method called PURGE. You can use that to purge a specific URL from the cache. You need to have purge access setup in squid.conf similar to manager access. Here is an example:
    acl purge method PURGE
    http_access deny purge !localhost

-n  Proxy Negotiate(Kerberos) authentication.
    Use kinit username@DOMAIN first to get initial TGS.

-N  WWW Negotiate(Kerberos) authentication.
    Use kinit username@DOMAIN first to get initial TGS.

-p port
    Port number of cache. Default is 3128.

-P file
    Request body. Using the named file as data.

-r  Force cache to reload URL.

-s  Silent. Do not print data to stdout.

-t count
    Trace count HTTP relay or proxy hops

-T timeout
    Timeout value (seconds) for read/write operations.

-u user
    Proxy authentication username

-U user
    WWW authentication username

-v  Verbose. Print outgoing message to stderr.

-V version
    HTTP Version. Use '-' for HTTP/0.9 omitted case

-w password
    Proxy authentication password

-W password
    WWW authentication password

--https
    Use Transport Layer Security on the HTTP connection.

--anonymous-tls
    Use TLS with unauthenticated (anonymous) certificate.

--cert file
    File containing client X.509 certificate in PEM format. May be repeated to load several client certificates.

--trusted-ca file
    File containing trusted Certificate Authority (CA) certificates in PEM format. May be repeated to load any number of files.

--params values
    TLS library specific parameters for the communication session. See the library documentation for details on valid parameters. GnuTLS: http://gnutls.org/manual/html_node/Priority-Strings.html If repeated only the last value will have effect.

--ping [options]
    Enable ping mode. Optional -g and -I parameters must follow immediately if used. Repeated use resets to default ping settings.
