Session Based Server Management (ASP.NET PROGRAM)

         Session contains a sequence of requests for various functions in different states. Requests in different states have different opportunities to turn themselves to be profitable. A scalable server should also provide different levels of Quality of service to requests in different states in each session so that profitable requests like order and checkout can be completed in a timely manner.
