Interface ServletRequestAttributeListener
- All Superinterfaces:
- 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.
