Oleg,
The port here is 21. I get this from the configuration of the FTP host
I have to connect to through the HTTP tunnel. I am not sure where the
SSL port comes in from!
FYI, the proxy we use is a Microsoft ISA server requiring NTLM
authentication. And except for

the rest of the piece works fine with httpclient-2.0.2 and HTTPClient
instead of ProxyClient, which we use to download files over HTTP in
the same application.
I had to move to 3.0rc2 since ProxyClient or
HTTPConnection#getSocket() were not available in 2.0.2
