Antes de la versi\u00f3n 2.0.0 de Pathling Server, el punto final \u2019/$result\u2019 de Pathling permite a un llamador que puede obtener cualquier ID de trabajo de exportaci\u00f3n as\u00edncrona v\u00e1lido proporcionar valores de par\u00e1metro \u2019file\u2019 que contengan secuencias de salto de ruta.
