Once the HTTP page handler class is fully identified, the ASP.NET runtime calls the handlers ProcessRequest to start the process. This implementation begins by calling the method FrameworkInitialize(), which builds the control trees for the page. This is a protected and virtual member of TemplateControl class, class from which page itself derives.

Next the processRequest() makes page transits various phases: initialization, loading of viewstate and postback data, loading of pages user code and execution postback server-side events. Then page enters in render mode, the viewstate is updated and HTML generated is sent to the output console. Finally page is unloaded and request is considered completely served.
