Nginx, amazon cloud drive, how to make it dl before serve?

I have webdav nginx with aliases to gdrive crypt and copy of it - amazon rclone crypt.

While gdrive is super fast, i can watch movies and seek, rewind, do whatever i want,
amazon is very very slow - it is good only to download, seeking rewinding is unusable.

How can i make nginx to first download requested file from amazon cloud drive mounted rclone fuse,
and than serve it to me through vps?

More of a nginx question. But I don’t think nginx can do it. Even if you enabled nginx cache, the first access wont be cached. Subsequent would be cached…

Wait for rclone to add the local caching. There is an issue for that.
