Adding UCDN Storage as an Origin With W3 Total Cache Plugin

WordPress plugin W3 Total Cache allows using UCDN Storage to host your WordPress data either as a backup or to serve your files from there. This will significantly improve the speed of serving your content since our storage service is located in the same DCs as our CDN nodes.

In case you want to use only our CDN service without using UCDN Storage, please check this tutorial: WordPress With W3 Total Cache Plugin

First, you need to create a CDN zone that points to your WordPress blog, then you can follow the steps below:

1. After the installation of the W3 Total Cache plugin, the CDN feature will appear under the “Performance” section in the Admin menu. Hover your mouse cursor over the “Performance” section, and click on the “CDN” button. 

2. Under CDN section jump to General Settings.

3. Enable CDN feature, choose Self-hosted/ File Transfer Protocol Upload and save all settings.

4. Under CDN section jump to Configuration.

5. You will see a dialog where you will need to fill in your FTP credentials of the created CDN storage at the Universal CDN panel. To get your UCDN Storage FTP credentials, please check this tutorial: Storage FTP Login Credentials

Please note that you need to select Plain FTP as an FTP connection type. In addition, it is important to note, that for FTP Path you need to enter the name of your container, since the FTP account is common for all UCDN Storage containers under your Universal CDN account.

6. After that you need to set the hostname from which your content will be served from Universal CDN. You need to enter either our default CDN Domain (e.g. 10001-32.s.cdn12.com) or your custom alias which you have configured. You can also choose whether the content should be loaded using HTTPS.

7. Now you need to sync your data to the cloud. You can do that using the following options:

You only need to migrate Attachments, wp-includes/files and theme files. In order to upload CSS and JS, you need to enable minify.
