19  * <p>
20  * A dummy request dispatcher object. This object allows
21  * much more flexibility with changing standards as well
22  * as changing requirements on specific projects. For
23  * example, if someone wishes to test a forward without
24  * actually doing the forward, a sub-class of this that
25  * allows them to test this.

29  * <br>
30  * Overall, this class is empty allowing all request dispatcher
31  * calls to be propogated to the real request dispatcher.
