By putting all the pieces together, the HTTP requests received are forwarded by the Web server to Django,django to accept them at the requested middleware layer. The views are then assigned to the appropriate view based on the urlconf pattern match, and the view performs the core part of the desired work, generating the response as needed with the model and/or template. The response then passes through the middleware layer for final processing, and finally returns the HTTP response to the Web server and forwards it to the user.
