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.
