Default Value 




Specifies the number of seconds between checks for expired sessions. 

Set this value lower than the frequency at which session data changes . 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. 



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


none; state is not preserved across restarts 

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. 

Applicable only if the persistence-type attribute of the session-manager Element element is memory.
