Expected Behaviour

Current Behaviour

TUS protocol supposes a leading HEAD request to retrieve file state on the server. Server supports this, but traefik converts these HEAD requests to GET, and then server rejects it. Thus, we cannot continue an interrupted file uploading.

Workaround: both UI and SDK always send files from scratch. It leads to:

• more user traffic
• possible filename conflicts (partially uploaded files are not autoremoved)
