Proxy working in CURL but not in WinSCP

Dear forum members,
I am migrating my communication scripts from curl to WinSCP, and there is one connection that does not work.
By examination of the logs of both tools, I see that CURL is using the GET method to the http proxy, while WinSCP is launching CONNECT.
Maybe this is the reason? In that case, how can I make WinSCP use the GET method?
Thanks in advance for your help

Find below the log of the two operations:
------------------- curl

Re: Proxy working in CURL but not in WinSCP

WinSCP does not support GET. Actually what curl does, does not seem like FTP session at all.
