Delete variable permanently

Mantis · December 11th, 2004, 09:12 AM

Hi,

I have created a login page (PHP) which send the information to the next page (POST) - When the user has done the updates, I have a button : Logout with this:

Logout.php:
<?php
session_start();
session_destroy();
unset($_SESSION);
?>
<html><head><title></title>
<meta http-equiv="refresh" content="0; URL=http://www.webpage.com/">
<meta name="keywords" content="automatic redirection">

My problem is that if I click the "back" button 2 or 3 times in the browser, I return to the menu page and IE asked if I want to refresh; if I click refresh, the variables are still there??

How do I stop this?

Got the reponse from a friend:
To permanently kill the variable used, place this lines:
session_destroy();
unset($_SESSION);
if(isset($_COOKIE[session_name()])) { setcookie(session_name(), '', time()-42000, '/'); }

to unset session, session_unset();
to transit session variables, to other page,
<a href="delete_page.php?<?php echo strip_tags(SID); ?>">next</a>

You also might wanna turn off caching for all pages that use the session, might help.

Many shoes,
