In my configuration, I want that the clients always try to connect back to the Server so the clients retries is set to -1.
But I want to be informed as soon as a client is disconnected. That's why my configuration is dispatch/callback/retries=0 Otherwise I'm not informed when a client is abnormally disconnected. So, I have a question, is there a way to know that a client has been normally disconnected or not ?
