Code:
<?php
 if (!isset($_SESSION)) {
     session_start();
 }
 // anti flood protection
 if($_SESSION['last_session_request'] > time() - 2){
     // users will be redirected to this page if it makes requests faster than 2 seconds
     header("location: http://www.example.com/403.html");
     exit;
 }
 $_SESSION['last_session_request'] = time();
 ?>

I've already tested this script as you higher the second It Will keep redirecting to

Code:
http://www.example.com/403.html

without any reason.
Can anyone tell me why?
