Yes, Total Commader do FTP upload over the http proxy:
this's the request send by total commander to the proxy when doeing an upload
put ftp://username:password@servername/filename
 
Can we include username and password in the url send by LibCurlNet like the above request 'put'?

This shows the proxy not allowing you to CONNECT to port 21 on a remote
machine.

This is not an upload. You can make libcurl do this as well, just switch off
the proxytunnel option. But again: this is not an upload so the comparison is
moot.

So, can that tool do FTP upload over your HTTP proxy or not?

You don't "upload" with GET.

No it doesn't. CONNECT expects the proxy to connect to the remote server and
then libcurl would proceed and communicate with that.
