# RequestDispatcher d = httpservletrequest.getRequestDispatcher("/servlet/CAM);
# requestDispatcher.forward(httpservletrequest,response);
If the url starts with a "/" then it is relative to the host otherwise, it is relative to the page loaded. So the request dispatcher will forward to
http://localhost:8081/servlet/CAM
If the request dispatcher is created without a leading slash like "servlet/CAM", then it would going to
http://localhost:8081/servlet/servlet/CAM
Am I right ? Please guide
