| * This class is a listener for both session creation and destruction, |
| * and for session activation and passivation. It must be configured |
| * via your web application's <code>web.xml</code> deployment |
| * descriptor as follows for the container to call it: |
| * |
| * <blockquote><code><pre> |
| * <listener> |
| * <listener-class> |
| * org.apache.turbine.session.SessionListener |
| * </listener-class> |
| * </listener> |
| * </pre></code></blockquote> |
| * |
| * <code><listener></code> elemements can occur between |
| * <code><context-param></code> and <code><servlet></code> |
| * elements in your deployment descriptor. |
| * |
| * The {@link #sessionCreated(HttpSessionEvent)} callback will |
| * automatically add an instance of this listener to any newly created |
| * <code>HttpSession</code> for detection of session passivation and |
| * re-activation. |
