sn (Session) Parameter

The sn parameter is a pointer to a Session data structure. This parameter contains variables related to an entire session, that is, the time between the opening and closing of the TCP/IP connection between the client and the server. The same sn pointer is passed to each SAF called within each request for an entire session. For a list of important fields, see Session Data Structure.
