reapIntervalSeconds

60

Specifies the number of seconds between checks for expired sessions. 

Setting this value lower than the frequency at which session data changes is recommended. For example, this value should be as low as possible (1 second) for a hit counter servlet on a frequently accessed web site, or you could lose the last few hits each time you restart the server. 

maxSessions

-1 

Specifies the maximum number of active sessions, or -1 (the default) for no limit.

sessionFilename

SESSIONS

Specifies the absolute or relative path name of the file in which the session state is preserved between application restarts, if preserving the state is possible. A relative path name is relative to the temporary directory for this web application.
