Sessions are created when you call request.getSession() or request.getSession(true) in your Servlet (provided an existing Session doesn't already exist -- otherwise the existing one would just be returned). One caveat is that the container automatically creates sessions when JSP pages are used, unless you specify session="false" in the page header. But without JSPs, the container will not create a Session for you.


Sessions are destroyed when they timeout or when you call invalidate() on them. The timeout period is up to the container. By default, Tomcat times out sessions in 30 minutes. But you can override this setting in web.xml with something like this:


 

      30
