Responses with a 1xx, 204 or 304 status also carry the body.\n\nOn a keep-alive or pipelined connection the client reads those bytes as the start of the next response. A front-end proxy that reuses upstream connections may then pair responses with the wrong requests."}], "lastModified": "2026-10-26T17:13:55.323", "sourceIdentifier": "9b29abf9-4ab0-4765-b253-1875cd9b441e"}
