Resumable upload about webdav-daemon

[couling]

At this time chunked upload is not supported. Checking the code, it would need to seek() just here:

WebDAV-Daemon/rap.c

Line 1262 in 93759c7

int ret = respond(RAP_RESPOND_CONTINUE);

but it doesn't. It would also need the appropriate header to be parsed and passed through...

And there I see a problem. I can't find anywhere in HTTP a way to make byte range based PUT or PATCH requests. There's no header nominated for it. @dumblob if you have a WebDAV client that does support resume on upload I'd be interested to know what headers it tries to send.

On the other hand this webdavd does support range requests on GET. IE downloads can be resumed as long as the content being downloaded is a file.

Unfortunately, I don't believe there's a way to implement the feature you're asking for so I'll close this issue. Feel free to re-open if you can find the right headers to support.

Unfortunately no WebDAV client I know of supports resumable uploads (and probably chunked uploads neither).

Some HTTP clients (e.g. curl) use a trick to overcome this issue, but it has its drawbacks - https://stackoverflow.com/a/32963259 . Some also prefer to (ab)use the freedom HTTP gives us: https://stackoverflow.com/questions/20969331/standard-method-for-http-partial-upload-resume-upload . There is also tus but I'm not sure about its compatibility with WebDAV.

Generally this is the problem which is killing WebDAV IMHO. But that's off topic here 😉.
