Cheetah: Keeping track of multiple connected clients

[aberba via Digitalmars-d-learn]

Does anyone know how to keep track of multiple clients in Cheetah 
socket lib such that one can directly message a client or 
broadcast to all connected clients.

Something like:

onMessage(... e)
{
...
   // send to all
   e.clients.broadcast (message);

...OR...
   // target a client
    e.clients[clientID].send(message);
}

Or any D lib with similar function.
