Routing is way that eliminates needs of mapping each and every URL with a physical file. Routing provide a way that’s enable developer to define URL pattern that maps to the request handler. This request handler can be a file (In application, its .aspx file) or class (In MVC its Controller class and Action method).

For example, http//domain/Employee can be mapped to http://domain/EmployeeInfo.aspx in ASP.Net Web application. And http//domain//Employee same URL mapped with controller and action method in MVC.

We can also configure (register) custom route by using extension method of MapRoute.

At least two parameters required in MapRoute. The Default parameter is optional.

You can also register multiple custom routes with different names. Below line of codes illustrate how to register multiple route.
