A ServletRequestListener can be implemented by the developer
interested in being notified of requests coming in and out of
scope in a web component. 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/**
