STOMP documentation says about NACK message
https://stomp.github.io/stomp-specification-1.2.html#NACK
NACK
is the opposite ofACK
. It is used to tell the server that the client did not consume the message. The server can then either send the message to a different client, discard it, or put it in a dead letter queue. The exact behavior is server specific.
What does "server specific" actually mean in the context of ActiveMQ? Where can the behavior be set?
