How does an application server maintain / store / save the session information?
The designer of a server is free to do this any way he/she likes. Typically the contents of a session is stored in memory but since every object stored in a session is supposed to be serializable, it can be written out to disk or to a database. JRun uses a "sessions" directory under WEB-INF to store serialized sessions, using the session ID as a file name. Bill
