Does web sockets only support 1 connection using IIS 8 Client - websocket

Question

i have a MVC asp.net web app.
It is hosted on my local network on a Windows 8.1 32bit OS.
I have found that SignalR only supports 1 client connection.
So, I removed SignalR and switched to web sockets.
However, this did not solve the problem.
Am I accurate in stating that Web Sockets only supports 1 client connection on this OS and IIS 8 Client?
Is the solution to use IIS Express because I had problems getting this to work and in the end ended up rebuilding my PC.
Is there no workaround for this issue?
This is my code:
In my Global.cs file:
public static WebSocketCollection clients = new WebSocketCollection();
In my handler:
public class MicrosoftWebSockets : WebSocketHandler
{
private string name;
public override void OnOpen()
{
this.name = this.WebSocketContext.QueryString["chatName"];
MvcApplication.clients.Add(this);
//clients.Broadcast(name + " has connected.");
}
public void SendImage(byte[] jpeg)
{
this.Send(jpeg);
}
public override void OnMessage(string message)
{
MvcApplication.clients.Broadcast(string.Format("{0} said: {1}", name, message));
}
public override void OnClose()
{
MvcApplication.clients.Remove(this);
MvcApplication.clients.Broadcast(string.Format("{0} has gone away.", name));
}
}
In my HTML page:
var conversation = $('conversation');
var url = 'ws://192.168.0.13:80/SocketHandler.ashx?name=John Doe';
ws = new WebSocket(url);
ws.binaryType = 'arraybuffer';
ws.onerror = function (e) {
$('#divSystemMessage').html('Problem with connection: ' + e.message);
};
ws.onopen = function () {
$('#divSystemMessage').html('Client connected');
};
ws.onmessage = function (e) {
liveViewIndex = 0;
desktopImage.src = 'data:image/jpeg;base64,' + base64ArrayBuffer(e.data);
};
ws.onclose = function () {
$('#divSystemMessage').html('Closed connection!');
};
public class SocketHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
if (context.IsWebSocketRequest)
context.AcceptWebSocketRequest(new MicrosoftWebSockets());
}
public bool IsReusable
{
get
{
return false;
}
}
}
