Copy between two S3 buckets using presigned url

Is there any implementation currently to copy objects between two buckets using presigned url? I am looking at IBM COS and AWS S3 as the two bucket endpoints


Are you reading or writing to the presigned URL?

If you are reading from it you can probably use the http backend or rclone copyurl.

I don’t think writing to a presigned URL will work with rclone as rclone will want to set metadata which won’t be in your presigned URL.
