- Keep data from a failed download instead of discarding it on retry in some limited cases when we know it's ok (currently only HTTP 200/206). Prior to this change on failed transfer the tool truncated any outfile data written before retrying the transfer. This change adds an exception for HTTP downloads when the user requested auto-resume, because in that case we can keep the outfile data and resume from the new position. Reported-by: tkzv@users.noreply.github.com Fixes https://github.com/curl/curl/issues/18035 Closes https://github.com/curl/curl/pull/18665
