If you are looking for ASP.NET MVC Request Response processing , please read the following:

ASP.NET MVC( MODEL VIEW CONTROLLER ) is an architecture to develop ASP.NET web applications in a different manner than the traditional ASP.NET web development. The entire ASP.NET MVC architecture is based on Microsoft .NET Framework.
Like a normal web server interaction, MVC application also accepts requests and responds to the web browser in the same way.
Step 1: IIS takes each HTTP request and invokes ASP.NET that invokes UrlRoutingModule
Step 2: UrlRoutingModule starts routing system. Then routing system parses the incoming Url and constructs a Request Context and searches RouteTable. MvcRouteHandler helps for passing the Request Context which includes parameters parsed from Url and provides access to Request and Response objects.
Step 3: MvcRouteHandler then invokes DefaultControllerFactory which follows a naming convention to choose the correct Controller(C) class for a given request. Controller invokes the correct Action Method.
Step 4: Controller interprets with the Model(M) which manages the behavior and data of the application domain, responds to requests for information about its state. Then returns an ActionResult object and inform the View(V) to change as appropriate.
