Hi, Re: http://community.jboss.org/wiki/HotRodProtocol I've updated the wiki with the following information: - We know differentiate between request and response op codes to make the protocol more flexible - see pt2 email thread for further details. - Removed total body length and now all fields are accompanied by a length field. - Flags combined with XOR ops. - Added encoding based on http://community.jboss.org/wiki/RemoteCacheInteractions - Updated example at bottom. - Added event handling for cluster formation and cluster formation + hashcodes notifications.
