     * A ServletRequestAttributeListener can be implemented by the
     * developer interested in being notified of request attribute
     * changes. Notifications will be generated while the request
     * is within the scope of the web application in which the listener
     * is registered. A request is defined as coming into scope when
     * it is about to enter the first servlet or filter in each web
     * application, as going out of scope when it exits the last servlet
     * or the first filter in the chain.
     * @since Servlet 2.4

public interface ServletRequestAttributeListener extends EventListener {
    /** Notification that a new attribute was added to the
     ** servlet request. Called after the attribute is added.
    public void attributeAdded(ServletRequestAttributeEvent srae);

    /** Notification that an existing attribute has been removed from the
     ** servlet request. Called after the attribute is removed.
    public void attributeRemoved(ServletRequestAttributeEvent srae);

    /** Notification that an attribute was replaced on the
     ** servlet request. Called after the attribute is replaced.
    public void attributeReplaced(ServletRequestAttributeEvent srae);
