in this case, it might be easier to remove the cache headers from the
request on the way in.  so, try something like

  $r->headers_in->unset('If-Modified-Since');
  $r->headers_in->unset('If-None-Match');

so that the server isn't aware of any caching on the client (as opposed to
asking the client to behave in such and such a way).
