Nginx configuration for synchrony is not correct

[Sergey Mikhnevich]

This question is in reference to Atlassian Documentation: Running Confluence behind NGINX with SSL

I think there is an issue with /synchrony configuration. One should conditionally send "Connect" header to 8091 upstream. If you always send "Connect: Upgrade" you will and up with not working static js files.

For example this url will return 404

https://confluence.example.com/synchrony/resources/js/vendor/sockjs.min.js

So you need to make configuration as in nginx documentation example http://nginx.org/ru/docs/http/websocket.html

http {
    map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }


server {
....
    location /synchrony {
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://localhost:8091;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
		# Note using $connection_upgrade variable
		# It is not set and header is not passed to upstream for static file requests
        proxy_set_header Connection $connection_upgrade;
    }
}

This did not work for us on Confluence 6.0.7
