 ``hello_world`` is a functor class which handles HTTP requests.
 All the operator does here is return an HTTP response with HTTP code 200
 and the body ``"Hello, <ip>:<port>!"``. The ``<ip>`` in this case would be
 the IP address of the client that made the request and ``<port>`` the clients port.
+If you like to send an other status have a look at the function
+``set_status(status_t status)`` from connection.
 
 There are a number of pre-defined stock replies differentiated by
 status code with configurable bodies.
