asp.net-mvc - ASP.NET MVC and Web Forms registration

Question

How does IIS know when to route a requests to the ASP.NET MVC framework and the not the Web Forms framework?

Looking through the Web.config of an MVC project I can't see any modules or handlers that are registered, and nothing the Global.ascx seems to do it. So I am at a bit of a loss as to how the system decides which should be used to route a request.

Answer 1

在查看 MapRoute 方法后，系统注册了一组路由，这些路由将匹配的请求卸载到 IRouteHandler。IRouteHandler 然后返回一个实际处理最终请求的 IHttpHandler。

到目前为止，这是我的理解，所以它可能不是 100% 正确的。
