routing in mvc 4

Hi Sam,

ASP.NET MVC routing is a pattern matching engine that is responsible for mapping incoming browser requests to specified MVC controller actions. When the ASP.NET MVC application launches then the application registers one or more patterns with the framework's route table to tell the routing engine what to do with any requests that matches those patterns. When the routing engine receives a request at runtime, it matches that request's URL against the URL patterns registered with it and gives the response according to a pattern match.

When the MVC application launches the Application_Start() event handler of the global.asax execute that call the RegisterRoutes() method from RouteConfig class under App_Start directory (App_Start/RouteConfig.cs). The RegisterRoutes() route has a parameter that is a collection of routes called the RouteCollection that contains all the registered routes in the application. The following represents the default method that adds routes to the route table.

• Route Name:A route name may be used as a specific reference to a given route.
• URL Pattern: A URL pattern can contain literal values and variable placeholders (referred to as URL parameters). The literals and placeholders are located in segments of the URL that are delimited by the slash (/) character.
• Defaults:When you define a route, you can assign a default value for a parameter. The defaults is an object that contains default route values.
• Constraints: A set of constraints to apply against the URL pattern to more narrowly define the URL that it matches.

Hi sam,

You can create own routing by using MapRoute above of the default routing as:

In the above I have added a AboutUs routing with controller 'Account' and Action 'AboutUs'

You can request for about us as
