How to handle InvalidAuthenticityToken

Scenario:

1. Log in a user. 2. Go to a page with a form. 3. Open a new tab and log out the user. 4. Go back to previous tab and submit form. 5. It throws InvalidAuthenticityToken before getting to my login code. I need to redirect the user to a log in screen. What's the best way to capture this and handle this?
