i'll assume that you have, say you have, 3 "entry points" thoughout your app:
"subscribe", "unsubscribe" and "admin".
the controlling servlet has to check for a null session
if it is null at those particular entry points, set a unique value
if it isn't null at those points - send the user to the right places to "check in"
or log in again
you've probably got something like this in place for the navigation and direction
within the servlet, but here 'tis anyway:
RequestDispatcher rd;
rd = getServletContext().getRequestDispatcher(pageValueSetInGet);
// AND CHECK HOW THIS WORKS WITH BOTH BROWSERS
rd = forward(request, response);
OR
rd = include(request, response);
