Session description

Hijax is all about applying progressive enhancement to Ajax. In the Hijax model, JavaScript isn’t used for advanced intensive processing. Instead, the XMLHttpRequest object acts like a dumb waiter, passing information backwards and forwards between the client and the server. By hijacking the regular functionality and replacing it with an enhanced Ajax version, you can be assured that your website will work with or without Ajax.
