I made a website, behind CloudFlare, and sometimes I get an early terminated (nginx 499) request, which is really hard to work around in the codebase.
This happens in about 1 out of 4000 requests.
What I would like to ask is if this is normal or not? CloudFlare support told me that 499 happens when something between CF and the server drops the connection. I'm not on AWS, not on a load balancer, but on a simple VPS with direct IP connection (no virtual routers, etc.)
