The functionality that we are trying to implement is to have a simple request handler that calculates either the sum or the product of a list of integers, and that is included in the data sent from the clients. Specifically, if a client sends the string 1, 2 ,4 to our server, then the server should send back 7 if it is to calculate sums, or 8 if it is to calculate products.

Every server implements some form of data processing, in addition to handling requests coming in from clients and sending the results of that data processing task to those clients. This prototype will therefore serve as a first building block for more extensive servers, with further complex functionalities.
