I am happy with PUT and GET. I hope there are no broken proxies in
real life that block PUT.

I see. But it might be more difficult with partial uploads. I suggests
to include the checksum of the changes file as a header (e.g.
X-Changes-Sha256: ...) - even for the upload of the changes file
itself. We have seen aborted uploads of changes files in the past.
Having the checksum in the header would make it easier to detect such
problems at least for less advanced implementations of the server.
Feel free to ignore the checksum header if you don't need it in dak's
implementation.
Cheers,
Torsten
