Typically the container will manage a pool of worker threads, that is it will create a bunch of thread ready to do work and then assign work to them as needed. It will then reuse the recovered thread for a new job later on. I'm not really sure what the question is.
When the request is received by the container then it creates a request and response objects and set appropriate value from the HTTP request to the request and then hands over to the request processing thread for further processing.Therefore the server's request processing is multithreaded.
