How to implement SignalR if there is more than one iis server?

Question

Is there support for a cluster of iis nodes when using SignalR? Or do I need some third party message bus?

Answer 1

Not yet, but they are working on it.

It's planned for the 0.4 release.

When ready, more information will probably be published in the wiki: SignalR and Webfarms on the wiki

Edit2:

Azure, SQL-Server and Redis are implemented.

Answer 2

We just implemented this addon in our application and so far it works flawlessly. It uses a RabbitMq instance to distribute the messages to other servers and is really easy to configure.

We haven't tried this on a production server yet.
