If you need an easy workaround, I would suggest

Use a URL like http://mywebsite.com/loadsomething.php?ajax=true and

$isAjax = $request->getParameter('ajax');

Or, if you are POSTing you can create a hidden field named "ajax" . Ofcourse these won't solve your problem forever but will work as a quick fix if you need this as soon as possible.

If you want to support only one redirect, you can create a flash variable as well.

Otherwise you can look at the source code of symfony:

http://trac.symfony-project.org/browser/branches/1.4/lib/request/sfWebRequest.class.php

On line 518 you can see the request object identifies the request to be ajax from the HTTP headers. So you have to find out that after the redirect why the same HTTP headers are not set properly.
