Upon session time out need to redirect to login page

In ThingWorx, I have set the session timeout to 15 minutes. After the session times out, the expectation is that ThingWorx will redirect to the login page. Alternatively, a pop-up should appear with the message "Session timed out. Please log in to continue" and an OK button. Clicking the OK button should then redirect to the login page.

Is there a way to implement this functionality? Please provide the code or implementation steps.
