Subject Re: Way to cleanup *before* session terminates ?
Date Thu, 31 Jul 2003 08:17:30 GMT
Sorry Charlie (ok, I couldn't resist :), but there isn't a way to do this in
Tomcat 4.x and lower.  However, the (current draft of the)  2.4 Servlet-Spec
has changed the behavior, and so in Tomcat 5.x you can define a
HttpSessionListener that will get called before the session is invalidated.
