You can only forward within the same server. If look at the description
of ServletRequest.getRequestDispatcher(), you should see that it takes
a relative path, not an absolute URL.
To invoke a servlet on a different server, you need to redirect instead
of forward. In other words, get the browser to send a new request to
the other server instead of making a local call on the same server.
res.sendRedirect("http://hostname/servlet/Testservlet");
