I would save the file to a temporary file locally and then upload it
using libURLftpUploadFile. This has worked fine for me in the past.
For debugging purposes, make a log field and use libURLsetLogField to
show all the logged data in that field. That way you will be able to
see whatever messages your FTP server is giving and that might give
you a clue.
