# See Global Unlock Sample for sample code.

# Set the HTTP proxy server properties.
# This is to connect via HTTP/1.1 using CONNECT method
ftp.put_HttpProxyHostname("192.168.1.127")
ftp.put_HttpProxyPort(8080)

# If the proxy server requires authentication...
ftp.put_HttpProxyUsername("myProxyUsername")

# for data transfers. It is not possible to use non-passive (active) mode
# for FTP over HTTP.
