Hi, I've previously asked about when logging out of a page in Internet Explorer and then pressing the BACK button, one would get a page has expired type page and I've gotten that to work. However, if I press the BACK button's drop down menu to go back more than 1 page, I won't get a page has expired warning and in fact, I am still able to see the cached page. Any ideas how to fix this?
Thanks

As I said in my last post, whe you asked before, in some cases its impossible. Some browsers will _NEVER_ requery on forward/backrequests.

I use
ob_start();
ob_end_flush();
and that helps. I just wrap them around my start_session();
