Configuring Squid

Once we have finished writing the redirector program, we need to configure Squid to use it properly. There are a few directives in the Squid configuration file using which we can control how Squid will use our URL redirector program. Let's have a quick look at these directives.

Specifying the URL redirector program

We can specify the absolute path to our URL redirector program using the url_rewrite_program directive. We can also specify any additional interpreter or command line arguments that the program expects. The following are a few examples:

Controlling redirector children

Once we have specified the redirector program, we...
