   * \brief A middleware function that can be registered at the server.
   *
   * It will be called before an incoming request is passed to any HTTPSCallbackFunction and may perform
   * operations like redirects or authentication.
   *
   * It receives the request and response object as well as a function pointer ("next") to pass on processing.
   * This allows chaining those functions. If next() is not called, the HTTPSCallbackFunction that
   * would match the request url will not be invoked. This might become handy if you want to intercept request
   * handling in case of missing authentication. Don't forget to call next in case you want to access your
   * resources, though.
