The RFC states that 416 should be returned if the requested range does not
overlap the file. This should not happen with the slice module. Even the
last slice should overlap the file.
The 416 (Range Not Satisfiable) status code indicates that none of
the ranges in the request's Range header field (Section 3.1) overlap
the current extent of the selected resource...
There are cases when the slice module does not even know the size of the file,
for example when requesting the first slice.
