signalr scaleout sending message to only particular client

As I went through the documentaion of signalr scaleout options having a backpane, i see the backpane job is to send the message from one server to all signalr servers. If so, if Server 1 wants to send message to particular client, the message goes to backpane and from there to all other servers(ex. server 2,3)..where the client 1 is connected with Server 1. So can we restrict this to send only from server1 to client 1. Also the other question, are the events like connected, reconnected also will be routed to backpane and to all other servers ?

thanks

If you are using a SignalR backplane, all messages will be sent to all servers. There is no way to configure a SignalR scaleout provider to only send messages to specific servers. It's all or nothing.

If you choose to forgo a backplane, you could of course configure SignalR to use its default in-memory message store and then manually send inter-server messages.

Events like connected/reconnected/disconnected do not involve publishing messages so no messages will be routed to all other servers.
