Session timeout

Written by Joseph Ottinger

Servlet sessions (and JSP sessions, too, since they're the same thing) have a timeout period controlled by a node in web.xml, in the following format:

<session-config>
    <session-timeout>60</session-timeout>
</session-config>

This represents the number of minutes since the session was last used, so each page that affects or accesses the session will reset this timer. Note that some J2EE containers use wildly different definitions for this behavior.
