Question

i have a jquery Ajax request happening on a page. On php side i am checking if the session is active and doing something. If the session is not active i want to redirect the user to another page in php(header redirect). how do i do it.

I know how to achieve it in javascript(i.e if session_fail then change window.location but is there something that i can do in php/cakephp

If I understand what you want to happen then this is how I’m implementing it. It’s in Prototype instead of jQuery but it shouldn’t take you long to translate:

new Ajax.Request('process.php', {
    on401: function(response) {
        var redirect = response.getHeader('Location');
        document.location = redirect;
    }
});

In your PHP, output the following if the session is inactive:

header('Location: http://example.com/login.php', true, 401);
exit;
