In MVC instead of Mapping URL to files you map URL to classes and these classes are called Controllers.
The Map rout is in Global.asax with this format
/Controller/Action/Id for example /Dinner/Edit/2
In view there is a Folder Per Controller and there is a view File for every action method.
Request -> Routing -> Controller -> ViewResult -> ViewEngine -> Response
Authentication is by user of ASP.NET Roles and the Data of user are in User.Identity.Name
