By default, Nginx doesn’t enable gzip compression for serving files. This is commonly used to reduce the filesize of CSS and Javascript files, if they haven’t been minified or pre-compressed. This guide will show you how to enable it per site for a Plesk 12.5 or Onyx based server.
Note: All philmorehost subscriptions (shared and VPS hosting) already have gzip enabled for all sites.
Instructions
- Login to your Plesk server.
- Select the domain you wish to enable gzip for from the left hand side.
- Click in Apache and nginx settings:
- Down the bottom, add the following to the “Additional nginx directives” field:gzip on; gzip_disable “MSIE [1-6]\.(?!.*SV1)”; gzip_proxied any; gzip_types text/plain text/css application/x-javascript application/javascript text/xml application/xml application/xml+rss text/javascript image/x-icon image/bmp image/svg+xml; gzip_vary on;
- Click OK to save.
You can verify that gzip is working by using your browser’s debug tools or a third party website such as GTMetrix.
