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

    ftp := chilkat.NewFtp2()

    ftp.SetHostname("ftp.example.com")
    ftp.SetUsername("login")
    ftp.SetPassword("password")

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

    // If the proxy server requires authentication...
    ftp.SetHttpProxyUsername("myProxyUsername")
    ftp.SetHttpProxyPassword("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.
    ftp.SetPassive(true)

    // Connect and login to the FTP server.
