//  To connect through an HTTP proxy, set the HttpProxyHostname

//  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:
hostname := '192.168.1.108';
