We have Nginx as a reverse proxy server to a Pydio server backend running with Apache2. We are attempting to upload a 50G file. The Nginx server, 1.14.0, is attempting to write the file locally to /var/lib/nginx/body/ rather than sending it directly to the backend. Our proxy server has a very small footprint of just 13G.

Is there an option to send the file directly to the backend without writing locally?

Thank you.
