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;
	ssl_protocols					TLSv1.2;
	ssl_ciphers						EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH+aRSA!RC4:EECDH:!RC4:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS;
	ssl_prefer_server_ciphers		on;
	ssl_session_cache				shared:SSL:10m;
	ssl_session_timeout				60m;

	add_header						Strict-Transport-Security "max-age=31536000";
	add_header						X-Cache "HIT from Backend";
	add_header						X-XSS-Protection "1; mode=block" always;
	add_header						X-Content-Type-Options "nosniff" always;

	proxy_headers_hash_max_size		1024;
	proxy_headers_hash_bucket_size	512; 
	proxy_redirect					off;
	proxy_set_header				Host $host;
	proxy_set_header				X-Real-IP $remote_addr;
	proxy_set_header				X-Forwarded-For $proxy_add_x_forwarded_for;
	proxy_set_header				X-Forwarded-Server $host;
	proxy_set_header				X-Forwarded-Proto $scheme;
	proxy_set_header				X-Forwarded-Host $host;
	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 :)
