How can manage php session after successful logout?

In my application has three web pages. 1.) login page. 2.) welcome page 3.) logout page

I have managed the session using PHP session object. In my application log-In and log-Out functionality is working properly.

Here problem is that: After successful logout when user click on browser back button from logout.php page, again he reach to welcome.php page Whereas he log-Out successfully. But I want to there page has been expired or should not to come back welcome.php page.

Thanks in advance.

If you use CakePHP 2, you can also just do

$this->response->disableCache();

that basically does the same thing than the answer given by Repox

Why dont you check the authentication on ur welcome page.

Example:

if($_SESSION['authenticated'] = true) include('welcome.php') else include('login.php)

Another better application will be to redirect using Headers. header('Location: ' (LINK) );

This is actually a bit tricky, but (as far as I'm aware) this has something to do with cache.

I managed to avoid this particular problem by adding some headers through PHP:

header("Cache-Control: no-store, no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
header("Pragma: no-cache");

These should of course only be set when the user is logged in, as caching should be considered a good thing normally.

you need to force it to refresh the page and not laod it from cache.

plus diffrent browsers handle this diffrently. try adding a second section to your doc on the browse page

<HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
</HEAD>
