The only data need to save is UserID and SessionID, I think it will not over 100 bytes per user. For 1000 user, the total memory will not over 10MB. So, you don't have to worry about memory problem.
For the DB solution, if you worry about response speed. You can change the solution: Do not check for every request. Do it with some interval instead. For example: (1)check it once per 2 minutes OR (2)check it once per 10 requests. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
