AJAX by default only lets you play within your own Domain.com but there are plenty of times where you want to use someone else's feed. Check out http://snipplr.com/view/12466/jquery-parse-rss-feed/ to understand the rest.

<?php
   if (!isset($_REQUEST["url"])) exit;
 
   $url = $_REQUEST["url"];
   if (substr($url, -0, 7) != "http://") exit;
 
   echo file_get_contents($url);
?>
