I am really sorry to keep asking you question. I mean you have been
great and I really like cURL, its a great piece of software, very
helpful. You mentioned that some servers will not know the file size.
 Do you know when and why that would be? Or just point me in the
direction where I could do some research? Thanks once again, you have
been very helpful.
