CGI is not a server. Apache, IIS are examples of web servers.

If you are using Apache (this is incredibly likely if using fastCGI), then using this in your .htaccess file will redirect requests from mydomain/index/id/1/sort/a to mydomain/index.php?id=1&sort=a in the background, without the user knowing:

RewriteRule ^index/id/([0-9]+)/sort/(a|d)$ /index.php?id=$1&sort=$2 [NC]

Hopefully this is self explanatory.

.htaccess is a feature of apache, for which you may need to enable AllowOverride in httpd.conf
