[Zope] Sessions: without cookies? url rewrite?

Hi, what is in the future of using Sessions with Zope? I am mostly talking about the events of using session without cookies - and how do we pass the session id around? At the moment it seems that without cookies the id has to be included in the form or links manually - since there is no mechanism to do the same as in php's url rewrite. Has anyone yet solved this or is there any ways to go around this? -huima
