I think the cache control is correct, at least this specific resource must be revalidated each time. My only concern is that even if the resource has been revalidated and the origin server tells that the resource is still valid and there is nothing to download (304 Not modified, no response body), ATS consumes an extra 8192 bytes block from the cache and also writes a huge amount of data to the disk. **Origin access log** ``` 161.35.24.62 - - [20/Sep/2022:06:26:40 +0000] "GET /path/x.js HTTP/1.1" 304 0 "https://x.y.z/path/index.html"; "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36" "x.x.x.x, x.x.x.y" rt=0.018 uct=0.000 uht=0.017 urt=0.017 ``` More precisely, it writes around 500 MB to the cache storage after this specific request and I'm wondering if this is normal and won't affect server performance under high load? -- This is an automated message from the Apache Git Service.
