4/83.4.3.2 Not Stateless
HTTP is stateless, i.e., a WWW server does not keep any state information about users or clients because every document is retrieved independently. HG-CSP is session oriented and keeps state information about the session, i.e., about the user, the preferred languages, the client used etc. This is again important for synchronous communication because users see who else is logged on to the Hyperwave server, and send messages to them.
