ASP.NET Routing Content Map

ASP.NET routing enables you to use URLs that do not have to map to specific files in a Web site. Because the URL does not have to map to a file, you can use URLs that are more easily understood by users.

The MVC framework uses routing to link URL patterns to controllers instead of to Web pages. Because of the special way in which the MVC framework uses routing, some topics apply only to Web Forms applications and some apply only to MVC applications.
