These options will convert your operation into a HTTP PUT over the HTTP proxy,
and your proxy obviously is good enough to deal with that.

These options will make a HTTP CONNECT "through" the proxy and then it'll send
the proper FTP commands to the remote server.

These two requests are *vastly* different from each other. Using -v and
CURLOPT_VERBOSE will reveal this.
