    January 12, 2021

    Using a Content Delivery Network (CDN) will allow site images and assets (JSS and CSS) to be served from the CDN Point of Presence nearest to the customer. This will improve load times for your site. Managed WordPress and Managed WooCommerce sites plans include the Nexcess CDN.

    Step 1: Activate CDN Enabler

    1. Log in to your WordPress admin panel.

    2. From the admin panel, select Plugins > Add New.

    3. In the Search plugins field, enter “CDN Enabler.” In the CDN Enabler section, click Install Now. If the CDN Enabler plugin is already installed on the site then you will not need to have to install you can just activate it.

    1. When the installation completes, click Activate.

    Step 2: Configure CDN Enabler

    1. From your WordPress admin panel, select Settings > CDN Enabler.

As long as the CDN Enabler plugin is active before the Nexcess CDN is enabled in the portal the CDN origin URL settings in CDN Enabler plugin will be automatically updated. If you are using the Nexcess CDN on a live domain that matches the site domain set in the site plan, then you could enable HTTPS for the CDN in the CDN Enabler plugin settings.

    2. In the CDN Base URL text box, type your CDN origin URL.

    1. Click Save Changes and Empty Cache.

    If you do need to purge the content being stored in the Nexcess CDN you can purge the CDN directly from the portal in the performance tab.
