Enable Gzip in Amazon Linux
How to enable gzip on Plesk Nginx

To check if a web site have gzip enabled, run

curl -I -H 'Accept-Encoding: gzip,deflate' https://YOUR_DOMAIN.EXTN

When you have no GZIP enabled, you will see error as follows

boby@hon-pc-01:~$ curl -I -H 'Accept-Encoding: gzip,deflate' https://serverok.in
curl: (7) Failed to connect to serverok.in port 443: Connection refused
boby@hon-pc-01:~$ 

With gzip enabled, you see something like following

boby@hon-pc-01:~$ curl -I -H 'Accept-Encoding: gzip,deflate' https://serverok.in
HTTP/1.1 200 OK
