    Unfortunately, unless you already have other CGI scripts running in the same place, this is harder than just plopping a file somewhere – some stuff has to be configured in the web server to make it possible: apache settings, the .htaccess file, permissions, and so on.

    Make sure you read the Apache Tutorial on CGI to be up to date with what needs to be configured.
