in what sequence does mvc model view controller gets called or is processed when a http request is made. 

Receive first request for the application ->  Perform routing -> Create MVC request handler -> Create controller -> Execute controller -> Invoke action -> Execute result


In an ASP.NET Web site, URLs typically map to files that are stored on disk (usually .aspx files). These .aspx files include markup and code that is processed in order to respond to the request.

The ASP.NET MVC framework maps URLs to server code differently than an ASP.NET Web Forms page. Instead of mapping URLs to ASP.NET pages or handlers, the framework maps URLs to controller classes. Controller classes handle incoming requests, such as user input and interactions, and execute appropriate application and data logic, based on user input. A controller class typically calls a separate view component that generates HTML output as the response.
