SignalR How is a duplicate Connection Id handled?

Question

I have created my own IConnectionIdGenerator implementation which for simpicty in my webforms application names the client connection Id by the EmailAddress.ToL

Answer 1

Connection ids have to be unique. If you don't make them unique then one will kick the other connection offline. Internally we use the connection id as a unique identifier for a connection and we disconnect dupes.

If you get repeated 301 responses it's likely because you have a folder in your app called signalr, and it isn't directly related to sharing connection ids.
