-Using FTPS via an HTTP Proxy.
-Destination server is IIS (7.5 I think)
-File is created on remote server but the filesize is zero.
-Works ok when I do it via FileZilla
-Have tried changing WinSCP to Binary mode (no change)
I have also tried using the latest beta version 5.6.2 but that doesn't get nearly as far and fails with a "Proxy error: 503 Service Unavailable"
Any help would be much appreciated.
