Redirecting browser using AJAX

Is there a way to redirect a user to a page (login page in my case) when an AJAX query is made by the user to a server? The server is supposed to serve data only if the session is set or else the user should be redirected. I have tried sending a header("location:...") request but the browser handled it as a string (xmlhttp.response) rather than acting on it.

Not directly. Your callback function would have to handle it.

For example, if the server sends the text "LOGIN;/login.php;" then your onreadystatechange call back could have the snippet

if (xmlhttp.responseText.substring(0,6) == 'LOGIN;') {
    window.location.href = xmlhttp.responseText.split(";")[1];
    return;
}

If you're using a framework for the Ajax, this code could be in whichever callback gets the result of the Ajax call.

No. Not directly. You can return something special which should be handled as a redirect. But since the browser isn't looking to navigate and it won't.

In the callback function you can set the window.location to the new page if the session is not set.
