how can I use InternetWriteFile

Hi,

how can I use InternetWriteFile (or any other function/component) to send
(PUT not POST) a file using HTTP protocol to a URL ?
Until now I haven't see a working example (all I've see refer to POSTing a
file that, I think, requires an existing form and a CGI server at server
site).
What I want is the HTTP client to send any file it wants to my web site
(just like FTP does it)

thanks in advance
