pub fn resolve(header: &str, if_range: Option<&str>, size: u64) -> ResolvedExpand description
Resolve a Range header against a known size.
Declines in two directions, both deliberate and both permitted.
A multi-range request is answered whole. Honouring it means emitting
multipart/byteranges, which is a lot of surface for something no browser needs in
order to seek in a video or a PDF, and RFC 9110 allows answering with the whole
representation instead.
An If-Range is never honoured. The spec permits If-Range only with a strong
validator, and the only validator this daemon offers is weak, because SFTP reports
mtime in whole seconds. The specified outcome of that condition evaluating false is
the whole representation, not a 412.
