Routing In MVC

Routing In MVC:

ASP.Net Routing is setup in two places:

1.       In Web.config file. There are 4 sections in configuration file that are relevant to routing configuration:

         System.web.httpModules

         System.web.httpHandlers

         System.webserver.modules

         System.webserver.handlers

2.       In Global.asax, is a specific file that contains event handlers for ASP.Net application lifecycle events. The Route table is created during the Application_Start event as follows:

Protected void Application_Start()

{

                RegisterRoutes(RouteTable.Routes);

}

When an MVC application starts, the Application_Start() method is called. This in turn calls the RegisterRoutes() method, this method creates the route table.

The default route table contains a single route named as Default. The Default route maps the first segment of URL to controller, second to controller action, third to parameters.

Consider user enters the URL: …/Home/Index/8

Controller = Home

Action = Index

Parameters = 8
