According to the HTTP standard Transfer-Encoding should be a comma separated list, with the inner-most encoding first, followed by any further transfer codings, ending with chunked. Requests sent with: \"Transfer-Encoding: gzip, chunked\" would incorrectly get ignored, and the request would use a Content-Length header instead to determine the body size of the HTTP message. This could allow for Waitress to treat a single request as multiple requests in the case of HTTP pipelining. This issue is fixed in Waitress 1.4.0."}, {"lang": "es", "value": "Waitress versi\u00f3n hasta 1.3.1 analizar\u00eda el encabezado Transfer-Encoding y solo buscar\u00eda un \u00fanico valor de cadena, si ese valor no se dividiera, caer\u00eda y usar\u00eda en su lugar el encabezado Content-Length.
