// 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.
ssh.HttpProxyHostname := 'www.my-http-proxy.com';
ssh.HttpProxyPort := 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:
hostname := '192.168.1.108';
port := 22;

success := ssh.Connect(hostname,port);
if (success <> 1) then
  begin
    Memo1.Lines.Add(ssh.LastErrorText);
    Exit;
  end;

// Your application is now connected to an SSH server 
// through an HTTP proxy.
