local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local ftp = chilkat.Ftp2.new()

ftp.hostname = "ftp.example.com"
ftp.username = "login"
ftp.password = "password"

-- Set the HTTP proxy server properties.
-- This is to connect via HTTP/1.1 using CONNECT method
ftp.http_proxy_hostname = "192.168.1.127"
ftp.http_proxy_port = 8080

-- If the proxy server requires authentication...
ftp.http_proxy_username = "myProxyUsername"
ftp.http_proxy_password = "myProxyPassword"

-- FTP over an HTTP proxy requires that FTP Passive mode be used
-- for data transfers. It is not possible to use non-passive (active) mode
-- for FTP over HTTP.
