No cache custom tag not working

[Schmidt, Carl]

I have created a no cache custom tag to be inserted on various page.  Here
is the specific doStartTag method:
        public int doStartTag() {
                HttpServletResponse response = (HttpServletResponse)
pageContext.getResponse();
                response.setHeader("Cache-Control", "no-cache");
                response.setHeader("Pragma", "No-cache");
                response.setDateHeader("Expires", 0);

                return (SKIP_BODY);
        }
IE will continue to cache the .jsp

However, if I place the same set of response.setX directly into the .jsp, IE
will _not_ cache the page.  Why is the tag not working correctly?
