public interface ServletRequestListener
extends java.util.EventListener

Interface for receiving notification events about requests coming into and going out of scope of a web application.

A ServletRequest is defined as coming into scope of a web application when it is about to enter the first servlet or filter of the web application, and as going out of scope as it exits the last servlet or the first filter in the chain.

In order to receive these notification events, the implementation class must be either declared in the deployment descriptor of the web application, annotated with WebListener, or registered via one of the addListener methods defined on ServletContext.

Implementations of this interface are invoked at their requestInitialized(javax.servlet.ServletRequestEvent) method in the order in which they have been declared, and at their requestDestroyed(javax.servlet.ServletRequestEvent) method in reverse order.
