Note: This example requires Chilkat v9.5.0.51 or greater.

FTP through an HTTP tunnel (via an HTTP proxy server that supports HTTP tunneling).

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

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

var ftp = new CkFtp2();

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.HttpProxyHostname = "192.168.1.127";
ftp.HttpProxyPort = 8080;

// If the proxy server requires authentication...
ftp.HttpProxyUsername = "myProxyUsername";
ftp.HttpProxyPassword = "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.Passive = true;

// Connect and login to the FTP server.
success = ftp.Connect();
if (success !== true) {
    console.log(ftp.LastErrorText);

// Change to the remote directory where the file will be uploaded.
success = ftp.ChangeRemoteDir("junk");
if (success !== true) {
    console.log(ftp.LastErrorText);
    return;
}

// Upload a file.
var localFilename = "c:/temp/hamlet.xml";
