As with any good command line tool. Via proxy on localhost: squidclient http://stackoverflow.com/ Via proxy at example.com (could be an IP if needed): squidclient -h example.com http://stackoverflow.com/ Direct from the web server: squidclient -p 80 -h stackoverflow.com / NP: Depending on tool version you may or may not also need the "-j stackoverflow.com" or " -H 'Host:stackoverflow.com\n' " parameters to set the Host: header explicitly. The -H takes a string of extra headers separated by \n to add to the request.
