Why do HTTP 499 status codes appear in the nginx access log?
Issue
I see 499 status codes written to the nginx access log as shown below. Notice the HTTP 499 status and zero bytes written as a response.
[01/Jan/2017:00:00:00 -0500] "POST /Request/Path HTTP/1.1" 499 0 "-" "Mozilla/5.0 (X11; Fedora; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36"
