  "message": "Cache: send conditional requests only for cached 200/206 responses.\n\nRFC7232 says:\n\n   The 304 (Not Modified) status code indicates that a conditional GET\n   or HEAD request has been received and would have resulted in a 200\n   (OK) response if it were not for the fact that the condition\n   evaluated to false.\n\nwhich means that there is no reason to send requests with \"If-None-Match\"\nand/or \"If-Modified-Since\" headers for responses cached with other status\ncodes.\n\nAlso, sending conditional requests for responses cached with other status\ncodes could result in a strange behavior, e.g. upstream server returning\n304 Not Modified for cached 404 Not Found responses, etc.\n\nSigned-off-by: Piotr Sikora \u003cpiotr@cloudflare.com\u003e\n",
