+A networking protocol used by the legacy client/server. It is built on the message format of the [[https://www.maartenbaert.be/game-maker-dlls/http-dll-2/|Http Dll 2]] GameMaker extension. Every message may be optionally compressed with deflate. Client and server will always attempt to decompress messages. Messages start with a byte specifying its message type.
