TCP example : Echo - but what would the right practice be if you wanted to change to a chat server ?

[spexocta]

The example provided is an echo server - but what if i wanted to change it into a 'chat server' - that would send data from one client to all other connected clients than the one that sent the data ?

Am unsure how it should be structured correctly :

		// Convert the IP:socket for populating TCPAddr value.
		parts := bytes.Split([]byte(c.ipAddress), []byte(":"))
		ipAddress := string(parts[0])
		port, _ := strconv.Atoi(string(parts[1]))

		// Create the request.
		r := Request{
			TCP: c.t,
			TCPAddr: &net.TCPAddr{
				IP:   net.ParseIP(ipAddress),
				Port: port,
				Zone: c.t.tcpAddr.Zone,
			},
			IsIPv6:  c.isIPv6,
			ReadAt:  c.lastAct,
			Context: context.Background(),
			Data:    data,
			Length:  length,
		}

		// Process the request on this goroutine that is
		// handling the socket connection.
		c.t.ReqHandler.Process(&r)

Process() is where it calls the routine that in the end will send to that specific client - but if i instead looped through all clients that was not the sending client calling process on each of them something im not sure if that is the correct way ?

any ideas on how i would need to that the correct way ?
