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

To get the current request URL from within the master page you would do:

string s = this.Page.Request.FilePath; // "/Default.aspx"

I also recommend moving your navigation into the master page instead of the content page. This will make it easier to maintain / access.
