I have made a website wherein the user creates his account. If the user logsout he is directed to the home page. But the problem is if the user clicks on the back button then he is again directed to his account. The session again starts for the user which should not be the case. I ve used header caching at top of every page but still same problem continues.
What could be the possible solution.

Could you show us the logout code? would help alot

[agarwalsrushti]

PHP Code:

<p><a href="index.html" class="style14">Logout</a></p>

session_unset();

session_destroy(); 

I know there is some mistake even in the code.
I ve given the logout as a link. Can you help as how can i solve this problem.

PHP Code:

<?php

    header("Expires: Thu, 17 May 2001 10:17:17 GMT");    // Date in the past

    header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always modified

    header ("Cache-Control: no-cache, must-revalidate");  // HTTP/1.1

    header ("Pragma: no-cache");                          // HTTP/1.0

    

    session_start();

    // Unset session data

    //$_SESSION=array();

    // or...

    session_unset();

    // Clear the session cookie

    unset($_COOKIE[session_name()]);

    // Destroy session data

    session_destroy();

    

    header("Location: ../login_system.php");

    exit;

?>

This would be the code for logout and it is stored in a file called logout.php
Should i just redirect the user to this file when he clicks the logout link.

[phpdoctor]

mmm yes, you need to link the logout button to a different file.
im not sure why your code is not working.

This is how i do it:

PHP Code:

        $_SESSION = array() ;



        if (isset($_COOKIE[session_name()]))

        {

            setcookie(session_name(), '', time()-42000, '/') ;

        }



        session_destroy() ; 

to redirect i just use this:

PHP Code:

echo "<meta http-equiv='refresh' content='$time;URL=$url'>" ;

exit ; 

I obviously put this in to a function for easy use

Hope that helps,
