I can see this in my access log
66.102.6.215 - - [27/Oct/2016:05:05:27 +0000] "GET /wp-content/cache/minify/d9389.css HTTP/1.1" 200 80460 "https://example.com/" "Mozilla/5.0 (Linux; Android 6.0.1; SAMSUNG-SM-G935A Build/MMB29M) AppleWebKit/537.36 (KHTML, like Gecko) SamsungBrowser/4.0 Chrome/44.0.2403.133 Mobile Safari/537.36"
I can see the file size response to the client is around 80kb is this accurate?
