One thing you could try is this:
When the servlet sees that the session has expired, it can send back a
special page which immediately (i.e. when it is loaded) turns around and
makes a new request for the login page with the target frame set to _top.
Since the servlet had all the original data from the previous request, it
can build all of that into the new URL for the login page, so that you don't
lose any data.
Hope this helps.

Subject: servlet to set the target for the frame in the browser

should be loaded into the _top frame (=the complete browser window).

servlet request:

the frame target e.g. in case the session has expired?
