1891	$body_bytes_sent and $bytes_sent wrong during sliced subrequest	arnili@…		"When a partial slice hit triggers a subrequest to fetch more data from the backend, the $body_bytes_sent and $bytes_sent variables contain wrong information.

1.: Both variables should actually be 0. Data is sent to and accounted in the main request.
2.: The variables should certainly not be the same number.
