URL Rewriting is a server-side technique for mapping URL requests to request handlers.
Typically there is a direct mapping between request URL and the handler for that request. All requests that end in .php will be handled by a PHP script with the given name. Similarly, request paths that end in .html will typically be handled by a static file handler. The mapping between URL and handler is typically static, and depends solely on the extension of the URL Request.
