    // of the server initialization function as it offers more
    // control. Server objects can serve HTTP traffic, HTTPS
    // traffic, or both at the same time. The init_ex function
    // allows us to control this behavior.

    // The first argument is the local interface address. It
    // works just as the other examples but is shared between
    // HTTP and HTTPS. Then come the HTTP port and HTTPS port
    // arguments. If you want to disable HTTP or HTTPS you can
    // pass zero to its port argument. If the HTTPS port is
    // not zero, you need to pass the file names of the server's
    // certificate and private key.

    //   HTTP_Server *server = http_server_init_ex(
    //     HTTP_STR("127.0.0.1"), // HTTP and HTTPS port
    //     8080,                  // HTTP port
    //     0,                     // HTTPS disabled
    //     HTTP_STR(""),          // ignore
    //     HTTP_STR("")           // ignore
    //   );
    //
    // and if we wanted and HTTPS-only server we would
    // do this:
    //
    //   HTTP_Server *server = http_server_init_ex(
    //     HTTP_STR("127.0.0.1"), // HTTP and HTTPS port
    //     0,                     // HTTP disabled
    //     8443,                  // HTTPS port
    //     HTTP_STR("cert.pem"),
    //     HTTP_STR("privkey.pem")
    //   );

    // example.
