Once a new client connects to our server, TCP Server UDF attributes an identifier to the client.
An identifier (Connection ID) is a number between 1 and the value of max clients you set using _TCPServer_SetMaxClients, which you can also
get using _TCPServer_GetMaxClients. If
nothing is specified, the default value will be set (255).
Remember that Connection IDs are the way TCPServer UDF organizes the connected clients. It
is not very useful to manage this data.
