Welcome to our forums and many thanks for your interest in NetworkComms.Net.
It seems from what I can work out that each request from the client is treated in isolation by the server
A connection will be established on the first attempt and maintained automatically. There is no need to send keep alive packets.
To run code your specified code when the connection is closed please see NetworkComms.AppendGlobalConnectionCloseHandler and Connection.AppendShutdownHandler.
There is no need to create a connection token as again this is taken care of. Once you have an established connection please see Connection.ConnectionInfo.NetworkIdentifier.
We will attempt to add more tutorials in the future.
Hope the above helps, if you have any further questions please feel free to post back.
Regards,
Marc
