     * be created and sent, the response received and checked.
     * This method does <i>not</i> update the connection with
     * information about the tunnel, that is left to the caller.
     *
     * @param route     the route to establish
     * @param context   the context for request execution
     *
     * @return  <code>true</code> if the tunnelled route is secure,

     *          The implementation here always returns <code>false</code>,
     *          but derived classes may override.
