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.

sir take to instances and two function .But I show you one function
var SignalrConnection;
var ChatProxy;

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');
}
