Question

How do you prevent a page that is normally loaded through ajax to be loaded on its own? If for example in main.php you load via ajax “cart.php” and parse it to a local div. Would it be possible when an user attempts to directly load cart.php, the user is redirected to main.php instead?

You can detect if the page is loaded via ajax like this:

    if(strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
      /* special ajax here */
      header("Location: http://www.example.com/main.php");
    }
