public interface ServletRequestAttributeListener
extends EventListener
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.

servlet request. Called after the attribute is added.
attributeRemoved
public void attributeRemoved(ServletRequestAttributeEvent srae)
Notification that an existing attribute has been removed from the
servlet request. Called after the attribute is removed.
attributeReplaced
public void attributeReplaced(ServletRequestAttributeEvent srae)
Notification that an attribute was replaced on the
servlet request. Called after the attribute is replaced.
