It is really good that Elmish.Bridge has a way of closing and reacting to connections closings, but I want to be able to interact with multiple ws servers. I do not understand how Bridge.Send could be configured to send to a specific server.

Is that possible?

Bridge.Sender(msg,config.name,ignore,msg.GetType())

Ah, I see it has a function that could be used for that even though it doesn't show up in the editor.

Also, instead of the above, I just realized there is Bridge.NamedSend, sorry about that.
