You may have read our previous article on the Liquid Web Content Delivery Network, CDN Overview, and may be wondering how to actually use the Liquid Web CDN with your installation of WordPress. Utilizing the W3 Total Cache plugin, it is easier than you think. In fact, W3 Total Cache is among our list of recommended plugins for WordPress.

Although W3 Total Cache offers many performance enhancing options for WordPress, this article will be focusing on the CDN functionality provided. This article will also be written utilizing the Origin Pull CDN methodology, as compared to Origin Storage. Do not worry though, W3 Total Cache offers support for using Origin Storage as well.

At this point, we will go with the assumption that you have ordered a CDN account with us. However, if you have any questions about ordering or configuring a CDN with Liquid Web, do not hesitate to contact a Liquid Web Sales Engineer at the number below.

The process

The first step, if not completed already, is to install and activate the W3 Total Cache plugin. An article on installing WordPress plugins can be viewed in our piece entitled “WordPress Tutorial 3: How to Install a New Plugin, Theme, or Widget” should you require.

The next step is to open up the settings page for W3 Total Cache, and go to the CDN section. Here, there will be a check box to enable CDN functionality, and then a drop down menu for “CDN Type”. For this, select “Generic Mirror”. After this is done, click the save button.
Enable CDN

At this point, you will have an alert at the top indicating that you need to populate the “Replace site’s hostname with:”. This is the next step.

To populate this field, go to the CDN settings page for W3 Total Cache.
CDN settings page

Enter the CNAME used for your CDN account. This will usually be cdn.yourdomain.com. You do not have to click the “Add CNAME” button, as this is for if you were going to use different CDN accounts for things such as Cascading Style Sheets or JavaScript. Just click “Save All Settings”.
CDN configuration

After you save your settings, you will be prompted at the top of the page to deploy your changes. Do so at this time.

Once you have done that, you can verify that your WordPress installation is utilizing the CDN by looking at the source (or another tool in the browser) and checking if the domain used for images and other static content, such as Cascading Style Sheets, is the CNAME for your CDN.
