How does ASP.Net page works?

1. When a browser requests an HTML file, the server returns the file
2. When a browser requests an ASP.Net file, IIS passes the request to the ASP.Net engine on the server
3. The ASP.Net engine reads the file, line by line, and executes the scripts in the file
4. Finally, the ASP.Net file is returned to the browser as plain HTML.
