ASP.NET MVC: Route a .html request to an MVC route

For a SPA application I’m building I need to accept requests to .html files although I didn’t use static html files but razor views instead. To get this working inside ASP.NET MVC is a little bit harder than you would expect. So here are the required steps:

• Add a handler mapping  in your web.config that will point *.html requests to the TransferRequestHandler. Therefore add the following section to the<system.webServer> node:

	<handlers>
	<add name="HtmlFileHandler" path="*.html" verb="GET" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0"/>
	</handlers>

• Add a custom route. Open up App_Start/RouteConfig.cs and it to the RegisterRoutes call:

	routes.MapRoute(
	name: "Durandal App Views",
	url: "App/features/{viewName}.html",
	defaults: new { controller = "DurandalView", action = "Get" }
	);
