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).

Dart

import 'package:chilkat/chilkat.dart';

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

  final ftp = 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.
  try {
    ftp.connect();
  } on ChilkatException catch (e) {

  // Change to the remote directory where the file will be uploaded.
  try {
    ftp.changeRemoteDir('junk');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);

  // Upload a file.
