Reverse proxy configuration

[SKJoy]

Note: Not really an issue rather a help request.

Context: I am implementing MediaCMS for one of my clients and they want it through a reverse proxy, NginX in this case. The application works just fine without issues.

Argument: The client has an argument that the view count is not reflecting while NginX reverse proxy is being used! My opinion: This really not possible, right? No intermediate cache server is being used either.

Points

• I failed to find a sample NginX configuration file anywhere
• Need to understand how the view count works

Current NginX configuration:

server {
    listen                          *:443 ssl;

    ssl_certificate                 /etc/letsencrypt/live/DOMAIN.TLD/fullchain.pem;
    ssl_certificate_key             /etc/letsencrypt/live/DOMAIN.TLD/privkey.pem;

    proxy_set_header                X-Forwarded-Port $server_port;
    proxy_http_version              1.1;
    proxy_set_header                Upgrade $http_upgrade;
    proxy_set_header                Connection "Upgrade";

    client_max_body_size            100M;
    server_name                     DOMAIN.TLD;

    location / {proxy_pass http://APPLICATION_SERVER_IP_ADDRESS:80/;}

    access_log                      /WWW/DOMAIN.TLD/log/nginx/access.log combined;
    error_log                       /WWW/DOMAIN.TLD/log/nginx/error.log error;
}

Thanks in advance :) This is a WONDERFUL piece of software :)
