• Step 1)  The client browser sends request to the MVC Application.
• Step 2) Global.ascx receives this request and performs routing based on the URL of incoming request using the RouteTable, RouteData, UrlRoutingModule and MvcRouteHandler objects.
• Step 3) This routing operation calls the appropriate controller and executes it using the IControllerFactory object and MvcHandler object's Execute method.
• Step 4) The Controller processes the data using Model and invokes the appropriate method using ControllerActionInvoker object
• Step 5) The processed Model is then passed to the View which in turn renders the final output.
