Send Scaned Image, Web Socket

My problem is when using the ws Web Socket protocol that sends a giant string (a size chain of about 7 to 8 digits ex: 78872125 ) which is an image that I scan and the I turn it into base 64 and then I'll commit it to bytes in order to send it through the protocol.

This is the code section in c# where client.Send(Bytes, Bytes.Length, SocketFlags.None); is the part where you sent the message to a web socket in HTML5 .

private static void OnAccept(IAsyncResult result)
    {
        byte[] buffer = new byte[1024];
        try
        {
            Socket client = null;
            string headerResponse = "";
            if (serverSocket != null && serverSocket.IsBound)
            {
                client = serverSocket.EndAccept(result);
                var i = client.Receive(buffer);
                headerResponse = (System.Text.Encoding.UTF8.GetString(buffer)).Substring(0, i);
                Console.WriteLine(headerResponse);

            }
            if (client != null)
            {
                var key = headerResponse.Replace("ey:", "'")
                          .Split(''')[1]                     
                          .Replace("\r", "").Split('\n')[0]  
                          .Trim();

                var test1 = AcceptKey(ref key);

                var newLine = "\r\n";

                var response = "HTTP/1.1 101 Switching Protocols" + newLine
                     + "Upgrade: websocket" + newLine
                     + "Connection: Upgrade" + newLine
                     + "Sec-WebSocket-Accept: " + test1 + newLine + newLine;
                client.Send(System.Text.Encoding.UTF8.GetBytes(response));

                var i = client.Receive(buffer);
                //Console.WriteLine("Iniciando escanneo");
                string msasd = "";
                try
                {
                    List<string> devices = WIAScanner.GetDevices();
                    ICommonDialog instance = (ICommonDialog)Activator.CreateInstance(Type.GetTypeFromCLSID(new Guid("850D1D11-70F3-4BE5-9A11-77AA6B2BB201")));

                    Device device = instance.ShowSelectDevice(WiaDeviceType.UnspecifiedDeviceType, true, false);
                    if (device != null)
                    {
                        List<Image> images = WIAScanner.Scan(device.DeviceID);
                        foreach (Image image in images)
                        {
                            Bitmap objBitmap = new Bitmap(image, new Size(1250, 1550));
                            MemoryStream ms = new MemoryStream();
                            objBitmap.Save(ms, ImageFormat.Jpeg);
                            msasd = Convert.ToBase64String(ms.ToArray());
                        }
                    }
                }
                catch (Exception exc)
                {
                    //
                }
                //Console.WriteLine("Escaneo Terminado...");
                //Console.WriteLine("Iniciando Envio de paquete");
                byte[] Bytes = CodificarMensajeParaEnviar(msasd);
                client.Send(Bytes, Bytes.Length, SocketFlags.None);

                //Console.WriteLine("Envio Terminado");
                //Console.WriteLine("Se enviaron {0} bytes de informacion", msasd.Length);
            }
        }
        catch (SocketException exception)
        {
            throw exception;
        }
        finally
        {
            if (serverSocket != null && serverSocket.IsBound)
            {
                serverSocket.BeginAccept(null, 0, OnAccept, null);
            }
        }
    }

Good Now the script of my html where I get the message that is the scanned image in base64 that sent C # , where

ws.onmessage = function (evt) {
                cadena=evt.data;//aqui deberia de llegar mi mensaje
                cFunction(cadena);
            };

evt.data is the string that contains the result and well after that I send it to be stored by ajax to a route Laravel where there is no problem, the script complete is:.

<script type="text/javascript">
    function scannear(){
        loadDoc("ws://127.0.0.1:9000", myFunction);
    }
    function loadDoc(url, cFunction) {
        var cadena="";
        if ("WebSocket" in window) {
            var ws = new WebSocket(url);
            ws.onopen = function () {
                alert("Esta a punto de escanear documentos, asegurese de que la impresora este encendida");
                ws.send("scannear");
            };
            ws.onerror = function (error) {
                console.log('WebSocket Error');
            };
            ws.onmessage = function (evt) {
                cadena=evt.data;//aqui deberia de llegar mi mensaje
                cFunction(cadena);
            };
            ws.onclose = function () {
                $("#mymodal").modal();
            };
        }else{
            $("#mymodalchrome").modal();
        }
    };
    function myFunction(cadena) {
        $.ajax({
            url:'{{url('submitimagen')}}',
            type:'post',
            data:{imagen:cadena,_token:'{{csrf_token()}}',type:"documento"},
            success:function(data){
                if(data.ok){
                    setTimeout('location.reload()',1000);
                }else{
                    alert("error");
                }
            },
            error:function(error){
                console.log("error:"+error);
                alert(error);
            }
        });
    }
</script>

Well I hope you have understood with that bit of code since publishing everything would be very long and boring to read it for you.

  

Then the problem is only sending / receiving this giant data
Since with short chains like "hola mundo" everything works correctly
