I am trying to change the default Resin timeout of 30 min by adding a session-timeout tag in my web.xml file (under WEB-INF).   I followed the Caucho tutprial and also contacted Lunarpages support, but couldn't get it work (it keeps timing out at 30 min).  My web.xml looks like this (I am trying to change the session-timeout to 720 min).  Any help on this would be appreciated... thanks in advance!

</web-app>
