I have started using the Ethernet library. I am still in the process of understanding its implementation.
How are connected clients serialized? If 2 clients are connected at the same time, how do I know which one I am communicating with? When a client connects and submits a form, I want to make sure that I can isolate the communication between the server and client without interference of another client.
Depending on the implementation of the Ethernet library, I would either want to handle clients in serial or parallel (if possible).
