NoCat Loop

Hey All,
  I've installed NoCat on a machine (AuthServ/Gateway on the same 
machine for what it's worth) and have gotten most everything working 
great.  However I still have a major problem that will prevent this from 
being used in our infrastructure.  When a user logs in, the password is 
validated and the popup windows appears notifying the user that they are 
logged in, etc.  Instead of going to the originally requested page, 
however, the user is sent back to the NoCat login page.  Any ideas why 
this is?  Thank you all for your help.
