Other Notes

- Subclasses can use either {@link javax.servlet.http.HttpServlet#init(ServletConfig)} or {@link javax.servlet.http.HttpServlet#init()} for initialization just like any other servlet.
- The X-Response-Headers header can be used to pass through header values into the response. The value should be a URL-encoded map of key-value pairs. For example, to add a "Refresh: 1" header to the response to auto-refresh a page, the following parameter can be specified: "/sample?X-Response-Headers={Refresh=1}"
