request-specific data and keeps following the request from the beginning to the end of the pipeline.
Once the pipeline is started, httpapplication starts to trigger events one by one as shown in figure 6. each event processor is triggered. If an event is mounted, these processors execute their own tasks. the main task of this processing is to ultimately call the httphandler that receives the specific request. the processor (handler) is ASP. the core
measure is to check whether the requested resource can be read or browsed. If not, the request is rejected due to HTTP Error 403.2. Then IIS tries to use the Intergrated, Digest, or Basic method to identify this call. If the Intergrated method of Windows is used, Kerberos or NTLM will be used. If the request passes this step, it is ASP. NET's turn.

This method is the same as the previous ASP mode, that is, the server stores session information in the IIS process. When IIS is disabled or restarted, the information is lost.
