      public class RequestScope
      extends AbstractRequestAttributesScope

  Request-backed `Scope` implementation.

  Relies on a thread-bound `RequestAttributes` instance, which can be exported through `RequestContextListener`, `RequestContextFilter` or `DispatcherServlet`.

  This `Scope` will also work for Portlet environments, through an alternate `RequestAttributes` implementation (as exposed out-of-the-box by Spring's `DispatcherPortlet`.
