@ccaffy - additionally, this case caught my eye: ``` $ curl -I -H "Want-Digest: DOES_NOT_EXIST" -L https://localhost:1096/tmp/bigfile_5M_copy HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 5242880 Digest: unknown=dias4A== ``` The behavior is _almost_ correct -- I think it's returning the default (adler32) checksum in your case. The digest should be labelled as `adler32` and not "unknown", however. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1707#issuecomment-1377261418 You are receiving this because you are subscribed to this thread.
