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

VB.NET

Dim success As Boolean = False

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

Dim ftp As New Chilkat.Ftp2

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) Then
    Debug.WriteLine(ftp.LastErrorText)

' Change to the remote directory where the file will be uploaded.
success = ftp.ChangeRemoteDir("junk")
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)
    Exit Sub
End If


' Upload a file.
Dim localFilename As String = "c:/temp/hamlet.xml"
