    .net signalr-hub signalr.client
    When is the SignalR Hub OnDisconnected raised on server side, for the the .net client that crash or close without calling the Stop method?I am testing with the SignalR .NET client, not the javascript client. If I call the Stop method on the client, the Hub will raise OnDisconnected method immediately.But if I close the client or kill the process, the Hub will raise OnDisconnected method only after about 10 seconds. How can I detect instantly that the client is disconnected?

    Here is what I did. I used nuget to get the SignalR for my MVC4 project. Created a MyHub class in my controller (SignalRTestController.cs) In the Index Action, tried to broadcast a message from outside the hub and returned the view.

    I am trying to get a hold on SignalR and dove right into ChatRI started out by creating an mvc3 application and writing down my own implementation, keeping the basic functionality of the code from the git. It didn’t work out, so I revoked my own changes and ended up with an 1:1 copy of ChatR without any of my enhancements – still didn’t work. So I copy/pasted the source code into my project and it still won’t fire up.Chrome gives me the following 2 javascript errors:Uncaught TypeError: Object f

    I am working on an application to perform context synchronization between multiple web hosted applications using SignalR. The client machine instantiates a host using the SignalR Owin host and the applications connect to it with a no-proxy version of the JS Client. The issue I am having is that the “Client” applications are hosted in SSL environments the SignalR host is not (as it is constrained to the local machine). If I try to connect to the Hub from a standard non-SSL website hosting the

    When you use SignalR, in your HTML you need to reference the following two scripts: <script src=”~/Scripts/jquery.signalR-1.0.0.js”></script> <script src=”/signalR/hubs”></script>The second one is for a JavaScript hub proxy which will be auto generated. Everything works fine. However what happens if the JavaScript Hub Proxy generation is disabled somehow, perhaps by setting DisableJavaScriptProxies property (https://github.com/SignalR/SignalR/commit/7e974f4e92551a26f3e3e0

    I’m about ready to pull my hair out over this problem because all the guides show the same one or two solutions, which seem to be working for everyone but myself.I’m using SignalR in a Mono application, using Owin. I’ve set EnableCrossDomain = true in my HubConfiguration. I’ve set up a simple test page using javascript to connect. The negotiate and ping urls are loading without issue and seem to be replying correctly. However I get a cross domain error on the connect call.It’s definitely using m
