* Give ap_proxy_post_request as chance to act correctly on the status code

  by setting r->status temporarily to access_status. r->status might be
  different than access_status e.g. r->status could be HTTP_OK if e.g. we
  override the error page on the proxy or if the error was not generated
  by the backend itself but by the proxy e.g. a bad gateway.
