2.2.3.11 Extra Flags

The extra flags represent optional information about session state that a client requires a state server to store. A client can send this header when sending session data to a state server for the first time (that is, a Set_Request call). A value of "0" means no special action will be necessary for the session state data. A value of "1" means the client is creating an uninitialized session state item in the session state store.
