Remember it's a different architecture (Score 2)

WAP creates its own session ids, and that stops other serverside objects from sharing the same objects.

The thing to realize is that in WAP you have a proxy/gateway sitting between the cell phone and web server.

Judging from the Wireless Session Protocol Specfication at http://www.wapforum.org/what/technical.h tm it looks like most of the session handling stuff is geared to handling the connection between the phone and proxy.

In a perfect world we'd simply use cookies to track session just like in HTTP, but sadly these don't seem to work reliably yet in WAP. In the meantime, you'll have to resort to either passing session identifiers as form variables or else in the URL.

For anyone interested, I'm working on an overview article on how to add wireless users to your web service. The draft lives at http://dev.arsdigita.com/asj/wireless/.
