That's how it should be according to the Servlet 2.2 spec; you're only
allowed to pass on the request/response you received when you use the
RD to invoke another servlet.
However, Servlet 2.3 relaxes this and allows you to do what you want.
I suggest you take a look at the Proposed Final Draft, available at
Sun's Servlet site: <http://java.sun.com/products/servlet/>. Tomcat 4.0
implements this proposal.
