1. Connection (simple)

The following test will just test connection from a client to a server.

Client Application

The following code shows a very simple client, the client just initiates its connection to a given host on port 8000 and displays when ClientFramework::onConnect() is called.

Server Application

The following is the server for this test, it is also very simple. It just listenes on port 8000 and then print when clients connect and disconnect.
