Hi,

I'm having touble getting http put to work using the libcurl.dll (Windows).
The file is created, but has zero size. Uploading works fine however if I
use the curl command-line tool. I get the same results if I use the static
library.

Here is an excerpt of my implementation (which reproduces the problem), any
help is appreciated!

Best Regards,
David
