ok, what can we do here?
Let me tell you that I use ASP, so i can´t tell you nothing about PHP, but, if i´d had to do that, i´ll do the following:
1. I´ll put these meta tags in the head section to make the pages load every time instead of putting it in cache:
<head>
<meta http-equiv="Expires" CONTENT="0">
<meta http-equiv="Cache-Control"
<meta http-equiv="Pragma" CONTENT="no-cache">
</head>
2. Make a redirect page in the middle of the log off process, (just like in hotmail), when people press log out, direct them to a page. set the session vars to nothing and then redirect to the successfull log out page, these will help in some way.
then, when people press the back button, tha page will see that the session var is nothing and will send them to the login page.
that should work.

Use a session object to set the user's permission level, then just request the session object on each page. Here is an example.
