session help

tanjf

i have a problem with regard to sessions. This is my main code inside login.php

$_SESSION['name'] = $name;
$url = "Location: stu_login.php?PHPSESSID=". session_id();
Header($url);

Basically after i login, it shows the stu_login page. The problem is when i click on logout, it will go back to the login screen. But when i click on the back button on my browser, it goes back to the stu_login page.

When you log out does you php code destry the session ... if not that is possibly your problem ... the browser still sees your session and therefore doesnt direct you to the login page.

http://www.php.net/manual/en/function.session-destroy.php

that may be of some use if your problem is the above.

Yes i did the session destroy, my logout link has a href to a logout.php script which has the following code:

<?php
session_start();
header("Cache-control: private"); //IE 6 Fix
$_SESSION = array();
session_destroy();
$url = "Location: index1.htm";
Header($url);
?>

it still allows to me go back to my stu_login page after i pressed the back button from index1(login page). In the stu_login page the session id is still appended to the url. Pls advise tq
