I'm using Dropbox to download files from developing embedded devices. The devices use HTTP range request for split download due to hardware limitation.
・I changed the download link from dl=0 to dl=1.
・First, the device access to the download URL with range header, and get redirect URL. From redirect URL, the device receive split files with HTTP 200 status code.
・Secondly, the device access to above redirect URL with another range header, and occur download error with HTTP 403 status code.
Why receive 403 error code? How can I correct this issue?
