Website optimization from the cPanel control panel using mod_deflate

Introduction

• cPanel allows optimization of data transfer between the server and the website visitor using the Apache mod_deflate module. This module compresses the data before it is sent, using gzip.
• Enabling mod_deflate helps increase the loading speed of the site and reduces bandwidth consumption.
• The module can be activated either manually, by adding rules to the .htaccess file, or automatically through the cPanel administration panel. This tutorial presents the activation method via cPanel.

Requirements

• Access to the cPanel administration panel using the login credentials received via email.

Steps

• Log in to the cPanel control panel using your access credentials.

• After logging in, navigate to the Software section and click on Optimize Website.

• On the next page, select the desired option to enable mod_deflate:
• Disabled: The module is disabled; no compression is applied.
• Compress All Content: The module is enabled and compresses all types of files, including .js, .css, .html, .xml, .txt, etc.
• Compress the specified MIME types: The module is activated and compresses only the specified files. Enter the file types (MIME types) in the MIME Types field, in the format:
  • text/html for HTML files.
  • text/plain for text files.
  • text/xml for XML files.
  A complete list of MIME types can be found here . Separate the values with spaces, for example: text/html text/plain text/xml.
• After you have selected the desired option, click on Update Settings to apply the changes.

• After activation, a confirmation window will inform you that the settings have been successfully applied.

• Once you complete these steps, compression via mod_deflate will be enabled for all domains associated with your cPanel account.
