My site uses SignalR to communicate cross-domain. It worked great but I updated SignalR from 0.5.0 to 0.5.1 and my site broke.

Here's my script:

function start() {
    $.connection.hub.url = "http://otherdomain.com/signalr";
    $.connection.hub.start().done(function () {            
            $.connection.myHub.join();
    });
}

When script calls join - I see in Firebug that it is a POST (I believe it shoold be GET (jsonp) since it is cross domain) with no response.

EDIT: I tried $.connection.hub.start({jsonp: true}). Now I have can call server from client but calls from server don't execute on client.

I noticed that there are following calls: negotiate and send whereas locally (the same domain) there are: negotiate, connect, send.
