Is it possible to limit client session to one?

I didn't implement the application i'm now working on, so there is somme things that i d'ont understand wel.

This is how my WebSocket in C# code

public WebSocketServer CurrentWebSocket { get; set; }
...
`
// start the WebSocket
CurrentWebSocket = new WebSocketServer(this.SocketUrl + ":" + this.Port);
CurrentWebSocket.AddWebSocketService("/MyWebSocket");

            if (this.isSecured)
            {
                // Pks or P12 certificates are prefered
                CurrentWebSocket.SslConfiguration.ServerCertificate = new System.Security.Cryptography.X509Certificates.X509Certificate2(this.CertificatePath, this.CertificatePassword);
            }

            WebSocketListener.OnMessageReceive += WebSocketListener_OnMessageReceive;
            WebSocketListener.OnOpenReceive += WebSocketListener_OnOpenReceive;
            WebSocketListener.OnErrorReceive += WebSocketListener_OnError;
            WebSocketListener.OnCloseReceive += WebSocketListener_OnCloseReceive;

            CurrentWebSocket.Start();`

Once the WebSocket is started a, application user can connect to it such as:

` // Let us open a web socket
ws = new WebSocket(document.getElementById("url").value);

           ws.onopen = function()
           {
              // Web Socket is connected, send data using send()
				logtext("Connected");
           };
                                           
           ws.onmessage = onreceive;
                                           
           ws.onclose = function()
           { 
              // websocket is closed.
              logtext("Connection is closed..."); 
           };`

The problem i have is that if in my testing page i connect X times to my WebSocket, each after i will send a command i will receive the response from my service X times.

Is it a way to limit my websocket to have a unique session open at a time?

Start with the WebSocketServer setup and WebSocketListener event handlers shown in the issue. Trace how each opened connection is handled and how commands produce responses. Done means a second client is rejected or disconnected, so one open session receives each command response once.
