Optimize Website
Overview
This interface allows you to configure your server to automatically compress specified types of content when visitors access that content.
Note:
Your system administrator must enable the mod_deflate Apache module for this interface to appear in cPanel.
Manage compression
To disable compression of your website’s content, perform the following steps:
- Select Disabled.
- Click Update Settings.
To compress all of your website’s content, perform the following steps:
- Select Compress All Content.
- Click Update Settings.
To specify a list of types of content to compress, perform the following steps:
- Select the Compress the specified MIME types option.
- In the MIME Types text box, enter a space-separated list of the types of content that you wish to compress (for example, text/html text/plain text/xml).
Note:
- Image file formats (for example, .jpg and .png) already compress data. Do not include any image file formats in the list.
- Apache will compress PHP content if you enable the zlib.output_compression setting in cPanel’s MultiPHP INI Editor interface (cPanel >> Home >> Software >> MultiPHP INI Editor).
- For more information, view Wikipedia’s list of Internet media types.
Note:
cPanel saves your settings to a .htaccess file in your home directory. Your system administrator customizes these settings with the Apache FileMatch directive.
