asp.net form authentication ticket slidingExpiration code

Question

I want to be able to detect when the form authentication ticket updates due to the slidingExpiration flag being set to true. I need to call a backend service with the new expiration time. Does anyone know where the code is that re-validates the ticket and updates it with the new expiration time due to the slidingExpiration?

Thanks!
