Procedure Test
    Boolean iSuccess
    Handle hoSsh
    String sHostname
    Integer iPort

    Move False To iSuccess

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

    Get Create (RefClass(cComChilkatSsh)) To hoSsh
    If (Not(IsComObjectCreated(hoSsh))) Begin
        Send CreateComObject of hoSsh
    End

    // To connect through an HTTP proxy, set the HttpProxyHostname
    // and HttpProxyPort properties to the hostname (or IP address)
    // and port of the HTTP proxy.  Typical port numbers used by
    // HTTP proxy servers are 3128 and 8080.
    Set ComHttpProxyHostname Of hoSsh To "www.my-http-proxy.com"
    Set ComHttpProxyPort Of hoSsh To 3128

    // Important:  Your HTTP proxy server must allow non-HTTP
    // traffic to pass.  Otherwise this does not work.

    // Connect to an SSH server via an HTTP proxy:

    // Hostname may be an IP address or hostname:
    Move "192.168.1.108" To sHostname
    Move 22 To iPort
