    # Simple http server.
    # To start handling requests:
    # 1. Create a dealer socket
    # 2. Connect the socket to the server backend address provided in the options.
    # 3. Create a zhttp_request.
    # 4. Call zhttp_request_recv to accept a new request.
    # 5. Call zhttp_response_send to send a response.
    #
    # You can connect as many dealers as you want.
    # The Server is using simple dealer socket to route the requests.
    #
    # NOTE: when using libmicrohttpd << 0.9.34 the application might experience
    # high CPU usage due to the lack of MHD_suspend_connection and
    # MHD_resume_connection APIs. It is recommended to use this class only with
    # libmicrohttpd at least 0.9.34 in production.
