Question

the problem is that if the auth cookie has expired and the user clicks on a link that should open a popup using $.get than i get the login screen in the popup (same masterpage in another masterpage) instead of redirecting the whole page to the login screen

anybody knows how to fix this ?

Answer 1

ASP.NET MVC has the following property on it’s Request object:

Request.IsAjaxRequest()

This will (amongst other things) checks for the existence of the X-Requested-With header, and a value of XMLHTTPRequest. Checking this, along with checking for IsAuthenticated would allow you to modify your response appropriately.

What you do then is up to you:

1. Display a message to the user in the pop-up requesting that they log in again.
2. Handle the response and perform a redirect as per Pekka’s recommendation.
