This can lead to a potential for HTTP request smuggling/splitting whereby Waitress may see two requests while the front-end server only sees a single HTTP message. This issue is fixed in Waitress 1.4.0."}, {"lang": "es", "value": "Waitress versi\u00f3n hasta 1.3.1, implement\u00f3 una parte \"MAY\" del RFC7230 que declara: \"Aunque el terminador de l\u00ednea para los campos de l\u00ednea de inicio y encabezado es la secuencia CRLF, un receptor PUEDE reconocer un LF \u00fanico como un terminador de l\u00ednea e ignorar cualquier CR anterior\". Desafortunadamente, si un servidor front-end no analiza los campos de encabezado con un LF de igual forma que los que tienen un CRLF, puede conllevar a que el servidor front-end y el back-end analice el mismo mensaje HTTP de dos maneras diferentes. Esto puede conllevar a un posible tr\u00e1fico no autorizado y una divisi\u00f3n de peticiones HTTP, por lo que Waitress puede visualizar dos peticiones mientras que el servidor front-end solo visualiza un solo mensaje HTTP.
