I am unable to tell from your post if this is an actual program logic issue
or cache issue,  from what I read it sounds more like cache.

maybe take a look at http://www.perlmonks.org/index.pl?node_id=239698 (post
showing a full out no cache setup) and verify that you are setting cache
directives to force no caching on the sensitive pages?  If this is a
program logic issues can you please try to reword the question to be more
specific,  maybe with a real world example. If you need help with how to
set such cache settings in your cat app let me know and I can get into more
Cat specific details.

This is what is leading me to think it is a cache issue in entirety, as if
the page cache settings were set to nocache the browser should not display
the pervious page period.
