hmmm... if I understand correctly, that would suck. I suppose it would 
be implementation dependent (I am using eXist), but I would hope that it 
would be in order so a redirect would happen after the session variables 
are set - or do the redirect but still set the session variables ??

I will ask on the eXist list what can be expected.
