It seems I am confused about how RequestDispatcher works. From what I understand I think using a RequestDispatcher from within a Servlet or a Filter, is same - the request is viewed as a fresh request appropriately handled by Tomcat. This means, when I use RequestDispatcher(static_url).forward()+return in a servlet, it is the tomcat that is serving the static url, and in the same way as directly requested static urls. "If you're serving your own static content with your own servlet, then you could do this." -- I want RequestDispatcher to handle serving the static content in my own servlet. Please clarify.
