How to expire page in PHP when user logout
문제
I want to expire my previous page when end user clicks on LogOut or Back button of the browser.
해결책
If you include this at the top of all of your pages, it will require the client to always reload the content, making the back-button requesting a new copy of the page.
<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>
다른 팁
You could have some issues with the browser back button, because when clicked, some browsers simply don't reload the page from the server and displays the previous state of the page from the cache.
Destroy the session key with session_destroy();
