button back and session expired

I've all my site in PHP with POST method, for avoiding most user see what's
appening in the variables I pass trough the pages. (as some info shouldn't
be visible for most users).

What appens when I push the "return" button is an error message telling the
"page has expired". I know this is a problem with the POST method, as I've
seen thousand thread about this, but I can't change my code. So it's there
any way to let this message disappear, maybe working with the header of the
pages (cache expires.....anything else).

Please help !

1. If using session, add session_cache_limiter('private, must-revalidate');
2. Otherwise, add header('Cache-control: private');
