Httprequest --> inetinfo.exe --> response --> aspnet_wp.exe --> httpruntime --> httpapplication factory --> httpapplication --> httpmodule --> httphandler factory --> httphandler. processrequest ()

When an HTTP request arrives at the HTTP module, it does not actually process the request. You can append some information, intercept some information, or stop the request at this stage. After the HTTP handler is processed, You can process it again in the HTTP module and return the correct result to the client.
