Subject RE: Session Timeout
Date Fri, 05 Sep 2003 14:04:58 GMT
anything you set in WEB-INF/web.xml can be set in
CATALINA_HOME/conf/web.xml and these setting will be used on a global
basis, unless overriden at a lower level.
 
FWIW, I've always understood session-timeout to mean "after a period of
inactivity".  I mean really... how useful would sessions be if they
logged you out after n minutes, no matter your activity level?  Talk
about frustrating! "It doesn't matter that you've been using my site
continuosly for the past 30 minutes, I'm still kicking you off". That
sounds like 'session-duration' to me.
