Hi

I am trying to upload a file to a ftp site using following code. Problem is file is getting upload but there is no data. Can you plz advise where I am getting lost. Also my files are with big data, 2+ GB, as far as know this ftp upload will not effect on my cache.dat size. Plz correct if my understanding is not correct.
