How to use cross-domain connections (CORS - Access Control Allow Origin) with SignalR

Question

Using persistent connections and an ASP.NET JavaScript client, I am trying to connect to a sub-domain not the same as the one the page was served from.

ASP.Net Page

Answer 1

What really have solved my issue was:

1 - Add this to global.asax:

RouteTable.Routes.MapHubs(new HubConfiguration() { 
    EnableCrossDomain = true 
});

2- Set up the web.config of my web project to enable the cross-domain:

3- Then I change the implementation on my html, changing the $.connection() to as follow:

var connection = $.hubConnection('http://localhost.my:8081/signalr');
var chatHubProxy = connection.createHubProxy('chatHub');

Versions I'm using:

• signalR-1.1.0

• jquery.signalR-1.1.3.js

• dot.net 4.0
