Simple ASP. NET operating mechanism diagram

1. Enter a url request

2. the browser sends a request message to the server

3. The server processes the message. If it is js html cs, it will directly find the file on the hard disk and return it to the browser.

3. If a dynamic file is handed over to aspnet_isapi.dll extension processing extension, start ISAPIRuntime, start HttpRunTime, execute the PR method, create HttpWorkerRequest (mainly in the request message information), and then create the context object

An Application object is created through HttpApplicationFactory to process the entire request.
