SignalR - how to disable WebSockets (but keep other transports active)?

问题

In both a C# client and Web Client - how do I tell signalR - "Try everything but websockets"?

I have the following in my web code:

 window.hubReady = $.connection.hub.start({ transport: 'longPolling' });

But this is just javascript and longpolling; I'm looking for the configuration for both JS and C# clients to only remove websockets as a transport. How can this be done?

On the server:

 public class Startup    
 {
     public void Configuration(IAppBuilder app)
     {
         DisableWebSockets(GlobalHost.DependencyResolver);

         HubConfiguration hubConfiguration = new HubConfiguration();
         hubConfiguration.EnableDetailedErrors = true;
         app.MapSignalR(hubConfiguration);
     }

     public static void DisableWebSockets(IDependencyResolver resolver)
     {
         var manager = resolver.Resolve<ITransportManager() as TransportManager;
         manager.Remove("webSockets");
     }
 }

On the client:

$.connection.hub.start({ transport: ['serverSentEvents', 'foreverFrame', 'longPolling'] }).done(function () {...}

Edit - adding bracket
