        <div>On further investigation -- it looks like the client was
          closing the front-end connection. I need the back-end socket
          to remain open regardless of what the front-end is doing. Is
          there a way to accomplish this?</div>

                        <div>I'm attempting to have multiple requests to

                          avoid handshaking for each subsequent request.
