sessions and back button

[Stefano]

Hi,

I am developing a web site with a section only for registered users and
using sessions to control the access to these pages.
I have the problem with the "back" button of the browsers, especially
in IE.
When I go back within the controlled zone IE always display the message
"page expired" and mozilla displaying the advise that you are trying to
access to a post data page etc..

I am wondering if there is a way to avoid this "problem" a save the
users to think what to do when they see these messages, letting them to
go back and forth until they get out of the session.

Thanks a lot for any help,

Stefano

Hi,
For Ie, you can use this :

<?php
header("Cache-control: private");
?>
On the first linbe of your pages.
Bye,

Or far better IMHO
session_cache_l imiter('private , must-revalidate');

works better than the "header" function.
