How to connect cross-domain web-client and signalr hub

Question

How to connect Web-Client with Hub when SignalR Hub has Different Domain and Web-Client has Different Domain. Eg: Web-Client (http://ABC.com/appLogin.html) and SignalR Hub (http://XYZ.com:/appLogin.html) in other hand we can also take localhost but different port number for both, then how we can connect our client to hub and send broadcast message to all.

Answer 1

sir take to instances and two function .But I show you one function

var SignalrConnection;
var ChatProxy;

var SignalrConnection1;
var ChatProxy1;

function Connect() {
    ChatServerUrl = "http://localhost:58416/";
    var ChatUrl = ChatServerUrl + "signalr";
    //This will hold the connection to the signalr hub
    SignalrConnection = $.hubConnection(ChatUrl, {
        useDefaultPath: false
    });
    ChatProxy = SignalrConnection.createHubProxy('ChatHub');

    //This will be called by signalr
    ChatProxy.on("NotifyUser",function (temperature) {
        $('span').text(temperature);
    });

//connecting the client to the signalr hub
SignalrConnection.start().done(function() {
        GetWeather();
        alert("Connected to Signalr Server");
    })
    .fail(function() {
        alert("failed in connecting to the signalr server");
    })

}

function GetWeather() {
    //calling the GetWeather function on the signalr server
    ChatProxy.invoke('get_weather');
}
