I use php with ajax.

<?php
/*
* Suppose, user has entered both correct login and password
* then server response is TO **REDIRECT** to profile page
* 
/
 header('location:/');
/*
* 
* print <<<HTML
<scrpit> window . location = '/profile.php';</script>
HTML;
* also doesnt work    
**/
?>

The problem is that it does redirect, but leaves part of authorization page, and the result = is mixed profile + auth page

    When using AJAX, redirecting using header() will not work.

    This is what will happen:

    • Request is sent to your PHP page.
    • You send back a redirect header with location.
    • Browser fetches the redirected page.
    • Contents of the redirected page is then passed to your XMLHttpRequest object.

    What you need to do is:

    • Determine if the request is ajax by checking to see if $_SERVER['HTTP_X_REQUESTED_WITH'] has the value of xmlhttprequest. Most JS libraries will send this.
    • If it is not AJAX, redirect using header('Location: /')
    • If it is AJAX, send back a JSON response with a location and status code for your javascript part to redirect, or echo('location.replace("\")');
