An internal redirect which results in a 304 Not Modified being sent to

the client gets logged as a 200, because the final response code of the
redirect is not propagated to the request structure that is logged.
The logfile then lies about the response status, which is not good for
a webmaster trying to diagnose problems or monitor cache hits.
Fixed by promoting the internal redirect status.
