Apache Handlers
Included with all web hosting accounts.

Apache Handlers provide you with a way to set specific server side (apache) handlers to be used with certain files with specific extensions. Apache Handlers control how files with a given extension (such as .shtml or .cgi) are to be handled on the server. This is similar to creating a special .htaccess file for your site.

Tip: Do not get too wild with your Apache Handlers. Most web hosting companies do not allow this privilege. If you some day change web hosting companies you may end up changing your file names.
