I am new to asp.net MVC architecture
i want to know the application flow.
I have already gone through this link
http://msdn.microsoft.com/en-us/library/dd381612.aspx[^]

In this it is given that as user request a page ---
In the Global.asax file, Route objects are added to the RouteTable object.

I want to know the flow from request to iis.

My doubt is When user request a page of Asp.Net MVC How IIS know's that it is request for MVC application and not normal Asp.Net Application.

Please guid me

Have a look at this article as well

http://blogs.msdn.com/b/tmarq/archive/2010/04/01/asp-net-4-0-enables-routing-of-extensionless-urls-without-impacting-static-requests.aspx[^]

IIS inspects the incoming request and looks up the handler for the type, most items are mapped into aspnet_isapi.dll. IIS -> Virtual Directory -> Configuration -> Mappings

Quote:
URLs are mapped to handlers by IIS when the request is initially received. I'll refer to the ASP.NET handlers as managed handlers, and everything else as unmanaged handlers. A request with a managed handler will enter ASP.NET and be processed by the various managed modules in the pipeline. On IIS 6, a request with an unmanaged handler won't be processed by managed code. On IIS 7, a request with an unmanaged handler, also, won't be processed by managed code, at least not by default.

I'm just going to repeat a lot of what is in the article, have a read through...but it's along the lines of

IIS receives Request -> Determine Mapping for Request -> Pass Request to Managed Code -> Look up route table .. etc etc
