A Content Delivery Network (CDN) is a system of distributed servers that deliver web content to users based on their geographic location. By utilizing a CDN, you can enhance the performance and reliability of your WordPress website. If you are using a CDN solution, you can bind it to your WordPress installation in the Virtuozzo Application Management.
Depending on the application server you are using, the CDN binding process may differ. Below, you can find two instructions (based on the application server) for binding a CDN to your WordPress installation:
LiteSpeed-Based WordPress Installation
1. First, ensure that the LiteSpeed Cache plugin is active.

2. Go to the LiteSpeed Cache > CDN menu item and select the Other Static CDN tab.
Tip: If you are using the QUIC.cloud or Cloudflare CDN, you can use the dedicated tabs for these CDNs instead of the Other Static CDN tab.

3. Enable the Use CDN Mapping option and add your CDN URL in the corresponding field. This is the base URL for content that is served from the CDN. If needed, you can adjust the following options:
- Include Images – enable this option to serve images from the CDN.
- Include CSS – enable this option to serve CSS files from the CDN.
- Include JS – enable this option to serve JavaScript files from the CDN.
- Include File Types – specify additional file types to be served from the CDN.

Click Save Changes.
4. If using the multisite feature, repeat the same steps for each site in the network.
NGINX-Based WordPress Installation
1. Ensure that the W3 Total Cache plugin is installed and activated.

2. Go to the Performance > General Settings > CDN section in the WordPress admin panel.

3. Tick the Enable checkbox for CDN, choose CDN Type from the drop-down list, and click Save Settings.

4. A warning requiring you to fill out the “Replace default hostname with” field will appear. Click on the Specify it here link or manually navigate to the Performance > CDN section.

5. Replace site’s hostname with your CDN endpoint hostname and click Save Settings.

Tip: Unlike the LiteSpeed-based installation, you do not have to configure CDN for each site (if using a multisite network).
From now on, all of the newly created websites in the network will be served by CDN.
