I see in logs of the server
220.127.116.11 - - [31/May/2019:10:05:04 +0200] “GET /url.html HTTP/1.0” 304 - “-” “Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.96 Mobile Safari/537.36 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)”
18.104.22.168 - this ip belongs to Cloudflare
does my server give out 304 response code to Cloudflare? Or to Googlebot? How it work?
