This sample illustrates the use of a servlet controller
to direct requests to various servlets.

When the first.html page is browsed, three submit buttons
are displayed.  Each button invokes a servlet called Controller.
The Controller servlet forwards the request to three different
servlets, depending on which submit button was pushed.

The technique of using a controller servlet helps to organize
an application that require the collaboration of multiple
servlets.

This technique, when used in conjuction with Java Server Pages,
is the basis of the Model-View-Controller design pattern.
