Say I have a server that is linked up on a subscription with another set of servers. They all publish on the same channel a certain type of message when an event happens and act on that event. However, I don't want the server that sent the message to also receive it (since he is also subscribed to the channel - all peers) and process as if it is from one of the other servers.
What's the quick/correct way to identify a message a particular instance sent out so that when it is received via subscription to that same channel it can be ignored?
