Hola, now I have tested the UrlSession Adapter and confirmed that it works. ( Download from http://www.zope.org/Members/k_vertigo/Products/URLSessionAdapter ) While creating an instance somehow AccessRule was not created to the folder where I created the URL Session Adapter - so I had to create the Access Rule manually. If you do the same then just remember to give the URL Session Adapters ID to the Access rule... Now Zope creates - when needed - session id:s to the URL. So http://www.mydomain.com/foo/ will transform into http://www.mydomain.com/xytadsekhgs*session-id-here*hga/foo/ Not bad. Eventhough the php way of giving the session id as a parameter was sexier ,-) -huima
