* Hand out the same DH structure in ssl_callback_TmpDH set by
  SSL_CTX_set_tmp_dh_callback though once generated as we leak
  memory otherwise and freeing the structure up after use would be
  hard to track and in fact is not needed at all as it is safe to
  use the same parameters over and over again security wise (in
  contrast to the keys itself) and code safe as the returned structure
  is duplicated by OpenSSL anyway. Hence no modification happens
  to our copy.

* 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.
