[Phplib-users] How to disable browser caching

[Carl Y. <cyo...@le...>]

I have been to sites where, when you click on the browser's back button, you
are given a message that says "this page has expired" and you are thereby
forced not to use the back button to navigate the site.  I would like to
accomplish this same thing with my PHPLIB sessions, but for the life of me
can't figure out how to do it.  I've set the $sess->allowcache flag to 'no',
but that doesn't seem to do any good.  Does anybody know how to accomplish
this?

Thanks,
