will help you This actually had nothing to do with my code.
Using fiddler i was able to see that Visual Studio had its own signalr connection to each of the web pages that I was debugging. Specifically long polling to a url that contained "arterySignaLR" after a quick search on stackoverflow i found this post:

wish help you to fix your issue Your problem is that the LoadCompleted event is called immediately after the page has been loaded, but before it has been rendered. I don't know of any way to tell exactly when it's finished rendering, but you can use the Dispatcher to ensure your code is run after any rendering has occurred.
code :
private void Browser_LoadCompleted(object sender, NavigationEventArgs e)
{
    Dispatcher.Invoke(TakeScreenshot, System.Windows.Threading.DispatcherPriority.Background);
}

private void TakeScreenshot()
{
    //insert your screenshot code here

SignalR Between MVC SignalR Server and Windows Service SIgnalR Client

SignalR Between MVC SignalR Server and Windows Service SIgnalR Client

Any of those help I already know from asking here that I can have SignalR in a plain old Windows Service. I want to communicate between that Windows Service as a SignalR Client and a ASP.NET MVC SignalR Server. I used this hubs guide, It said , This solves the problem
On the client (Windows Service):
code :
protected override async void OnStart(string[] args)
        {
            eventLog1.WriteEntry("In OnStart");
            try
            {
                var hubConnection = new HubConnection("http://www.savitassa.com/signalr", useDefaultUrl: false);
                IHubProxy alphaProxy = hubConnection.CreateHubProxy("AlphaHub");

                await hubConnection.Start();

                await alphaProxy.Invoke("Hello", "Message from Service");
            }
            catch (Exception ex)
            {
                eventLog1.WriteEntry(ex.Message);
            }
        }
public class AlphaHub : Hub
    {
        public void Hello(string message)
        {
            // We got the string from the Windows Service 
            // using SignalR. Now need to send to the clients
            Clients.All.addNewMessageToPage(message);

            // Send message to Windows Service

        }

Any of those help I resolved this myself.
As I explained in question, for Entitlement login, I'm login to actual website login page. Once I logged in to login page, I receives authorization token from response in DocumentCompleted event. And I am using same token for subsequent REST calls.

So in the thread startroutine I'm doing a

this will help I think I fixed the issue by adding an [Authorize] attribute to my Hub class. It's only been a few hours, but my SignalR powered page is behaving much better.
