Changing a URL to the required format. URL rewriting allows URLs to be more easily remembered by the user. When the URL is entered into the Web server, the URL rewrite engine modifies the syntax behind the scenes to enable the appropriate Web page or database item to be retrieved. For example, to look up the definition for "path," a user friendly URL might look like computerlanguage.com/path
. The rewrite engine could turn it into the following syntax: computerlanguage.com/results.php?definition=path.
