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

You need to do one of the following to make it work:

• Set up $.connection.hub.url = 'http://subdomain.domain.com/signalr';, pointing to your subdomain.

• Enable cross domain on the server:

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