No, they don't ! The difference between them is who will do what and on
which side. In the former, sending request to the another resource will
be done on *server* side, so a browser doesn't even know about it. On
the contrary, the later tells a browser to redirect a request to the
another resource. That will be done on client side and involve
*additional* round trip back to a browser. As you can see, be careful
with doing either ways, as they differ.
Another drawback of using sendRedirect is that request's parameters are
lost, so the following page won't see them.
