HTTP request processing process in Asp.net page and Asp.net MVC

The specific HTTP request processing process in ASP. NET is clearly described in Zhang Ziyang's blog in the blog.ArticleIt is an extension based on his article.

There are two access methods for me. On the left side is the traditional Asp.net form page access method, as shown in the figure below: Asp.net MVC access method, which is handled by ihttphandler's handler at last.

In Asp.net page, any page has implemented ihttphandler, because the page itself inherits ihttphandler. In MVC, we use mvcroutehanlder to return mvchandler, finally, create the Controller in processrequest in mvchandler and activate the action of the corresponding request.
