Do Group servers / whisper servers, forgive me if I’m using the wrong term, play ping pong like the main server does? Currently I am staying connected to the whisper server indefinitely and it appears to drop connection after a prolonged period of time. Is one suppose to only connect when one needs to send a whisper? I am not finding any information on this matter. Would someone be so kind and fill me in either how they are doing it, links, or just a simple explanation.
About once every five minutes, you will receive a PING tmi.twitch.tv from the server (both chat and group irc), in order to ensure that your connection to the server is not prematurely terminated, you should reply with PONG tmi.twitch.tv. - Twitch IRC API
