Description

If a request has a Range header, read only the desired portion from the data volume, and return the segment with appropriate HTTP status (206) and headers (e.g., Content-Length: 10001, Content-Range: 1234-11234/100000).

Skip hash verification (this would be impossible without reading the whole block). If a client needs to verify content hashes, it can either retrieve the whole block ahead of time and compute the checksums of each segment, or retrieve ranges in order and compute the hash piecewise.

Dear Team, Could we please assign a higher priority to this issue? Keepweb is extremely slow while keepproxy performs decently but is handicapped by the lack of Ranges support. It is quite a basic thing to have. Thank you in advance. Best regards, -- Stanislaw

Speaking strictly only in private capacity here. This issue is very high on my wish list.
