please help!! I am using a call to session.abandon, to logoff a user, as this then calls my clean up routines in onsession_end, fine so far... but I am using the sessionID to log access, the problem is sessionID does not change once a new session is begun, following the session abandon... It does if the session times out, or if i manualy close the browser windows. Am i misunderstanding the nature of sessionID??
