ftp and/or WebDAV support - KoReader cloud support

clach04 commented 2 years ago

Implement as an ftp and/or WebDAV server with same dir browsing support

Technically interesting enhancement but unlikely to pursue. OPDS server has been implemented which offers search support in addition to browse and convert support - a superior option for clients that support OPDS.

Possible protocols to support:

ftp
sftp
webDAV

nginix with SabreDAV works with KoReader (lots of versions work but 2022.1 and 2022.8 known for sure).

Serves headers:

propfind for directory https://github.com/koreader/koreader/blob/83a2965d6b7b40575e7c0b060540ff6cd084b1ba/frontend/apps/cloudstorage/webdavapi.lua#L84
