Shinebayar G's questions

I've an Nginx web server running on 192.168.10.1 address. Also, I've pointed my domain to this server. This server has public IP NAT-d through the corporate network. I can access my website fine from an outside network using the domain name. However, I cannot access this website from the server itself or over LAN network (from 192.168.10.2 server)

For example, curl mydomain.example doesn't respond from the server itself or from secondary server 192.168.10.2

I can actually put this server's internal IP address inside both server's /etc/hosts and curl works fine. But I want to solve root cause if possible, anyone faced similar situations? What could be causing this issue?

this is my very first question and please excuse my poor English.

I was doing research about how can i improve my page speed and i found out about nginx gzip settings.

Below are my gzip settings from nginx.conf

gzip on;
gzip_disable "msie6";

gzip_vary on;
gzip_proxied expired no-cache no-store private auth;
gzip_comp_level 5;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript application/vnd.    ms-fontobject application/x-font-ttf font/opentype image/svg+xml image/x-icon
gunzip on;
gzip_static on;

I assume with these settings, nginx will serve .gz compressed file instead of original one if it exists. If not nginx will compress them when user requests them. Correct me if i'm wrong, am i on the right track?

My question is: Does Nginx compress original files every time new user requests it? Or does it serve cached/saved version of those compressed files?

Example: I have these files in my static folder.

/static/css/main.css
/static/css/main.css.gz
/static/js/main.js
/static/js/main.js.gz
/static/html/index.html

When userA requests index.html file Nginx will compress the file on the fly, But what if userB requests the same index.html file, does Nginx compress the file again or will it serve cached/saved version from somewhere?
