Tomcat 4.0 *does* support 304 (HttpServletResponse.SC_NOT_MODIFIED) when
serving static resources. It compares the file's last modified date to the
"Date" header included in the request, and returns 304 if appropriate.

For responses generated by any other servlet, it is totally up to the servlet
-- not the container -- to decide when to send a 304. This makes sense when
you remember that the container has absolutely no way to know if the page that
would be created by your servlet, this time, will change or not. You can
either make this determiniation yourself and send the correct headers, or
implement the HttpServletRequest.getLastModified() method and HttpServlet will
do it for you.
