<div><br></div>In nginx, 499 means "<span class="Apple-style-span" style="color: rgb(51, 51, 51); font-family: Verdana, Arial, sans-serif; font-size: 14px; line-height: 23px; ">client has closed connection</span>". However, guys know little about 499 as it's not defined by rfc2616 but by nginx.<div>
<br></div><div>When a client sent a request, and closed the connection without waiting for the response, a 499 code occurs. If there're a lot of 499s in your access_log, it's mostly caused by the slow back-ends (too slow for your users to wait). You may have to optimize your website performance.</div>
