  "message": "Upstream: different header lists for cached and uncached requests.\n\nThe upstream modules remove and alter a number of client headers\nbefore sending the request to upstream.  This set of headers is\nsmaller or even empty when cache is disabled.\n\nIt\u0027s still possible that a request in a cache-enabled location is\nuncached, for example, if cache entry counter is below min_uses.\nIn this case it\u0027s better to alter a smaller set of headers and\npass more client headers to backend unchanged.  One of the benefits\nis enabling server-side byte ranges in such requests.\n",
