The Servlet Specification states that doing an include will allow the developer
access to all of the Request, but give it limited access to the response.
Specifically it states that you have access to the output stream but *may not* set
header info:
"The included servlet can not set headers or call methods that affect the headers
of the response. Any attempt to do so should be ignored."
Servlet 2_2 spec section 8.3.
