What is ASP.NET Routing?
“ASP.NET routing enables you to use URLs that do not have to map to specific files in a Web site.”

Out of the box MVC Routing
− Routes.IgnoreRoute()− System.Web.Routing.StopRoutingHandler
− Routes.MapRoute()− System.Web.Mvc.RouteCollectionExtensions− Parameters
− string name – “MyUniqueName”− string url – “{controller}/{action}/{id}”− Object defaults - new { controller = "Home", action = "Index”} − Object constraints – new {id = “[0-9]+”}− string[] namespaces - new[] { "Myproject.MyControllers"}

DEMO – Out of the box MVC Routing

Customizing ASP.NET MVC Routing
− Three main areas for routing customization− RouteConstraints
− Implementing constraints that require more logic than RegEx− Created by implementing System.Web.Routing.IRouteConstraint
− Routes− Allow for control over how route data is parsed or route paths
are determined− Created by subclassing System.Web.Routing.RouteBase− Default is Route ex. RouteCollection.Add(new Route(…))
− RouteHandlers− Allow for preprocessing before default RouteHandler behavior
− ex. RouteData modifications

Routing Concerns
− IIS6 requires special attention− Add .mvc extension to aspnet_isapi.dll in ISAPI mapping− “{controller}.mvc/{action}/{id}”− Can use wildcard mapping, but performance is
questionable
