Hi,</p>
<p dir="ltr">In the nginx documentation (<a href="https://www.nginx.com/blog/websocket-nginx">https://www.nginx.com/blog/websocket-nginx</a>), it is recommended to set the 'Connection' header to 'close' (if there is no upgrade header) - from my understanding, this disables keep alive from nginx to the upstream - is there a reason for this?</p>
<p dir="ltr">Additionally, is keep alive the default behaviour when connecting to upstreams?</p>
<p dir="ltr">Thanks<br></p>
