Server side redirects and URL rewriting

Hi all,

I've just started testing my app with cookies turned off on the browser 
forcing Enhydra to use URL rewriting. It breaks in the few places I'm 
using ServerPageRedirectException to forward to a different PO because 
the session id is not automatically added.

Changing to using ClientPageRedirectException fixes this for my 
purposes, but I was wondering if this is a bug/oversight or deliberate 
design decision? I wouldn't expect to have to add the sessionid to the 
URL explicitly to use server side redirects. If it is a bug any pointers 
on where/how to fix it.

Cheers,
Geoff
