Does a MasterPage know what page is being displayed?

Question

When I navigate on a website utilizing MasterPages, does the application know what page I am on? If so, does it store it in an object I can access?

The reason I am

Answer 1

The navigation control, not the master page, should be in charge of what page is currently highlighted.

Either the page that is loaded should notify the navigation item who it is, or the nav control itself should keep track of it.

The point is that master pages are supposed to simply be a holder that content is displayed in. They aren't supposed to control anything.
