How to Integrate with W3 Total Cache

Introduction:

Integrating Apto CDN with W3 Total Cache is an effective way to enhance your website’s speed and reliability. W3 Total Cache is a powerful plugin designed to optimize WordPress performance through advanced caching mechanisms, and pairing it with Apto CDN ensures your static assets are served quickly from the nearest server location.

Prerequisites:

  • Ensure W3 Total Cache is installed and activated on your WordPress site.
  • You should have an active Apto CDN account configured with an API key.

Step-by-Step Guide:

  1. Access W3 Total Cache Settings:
    • Log in to your WordPress admin dashboard.
    • Navigate to Performance > General Settings.
  2. Enable CDN Support:
    • Scroll down to the CDN section and check the box to Enable it.
    • Select Generic Mirror from the dropdown menu as the CDN type.
  3. Configure the CDN Settings:
    • After enabling CDN, navigate to Performance > CDN.
    • In the Configuration tab, input your CDN details:
      • Replace site’s hostname with: https://s1.aptocdn.com/{domain}/
      • Replace {domain} with your website’s domain (e.g., https://s1.aptocdn.com/mywebsite.com/).
  4. Additional Configuration:
    • Ensure that Host attachments, images, CSS, JS and other static files are selected under the General section for optimal use of the CDN.
    • Save your changes by clicking Save Settings & Purge Caches.
  5. Verify the Integration:
    • Go to the frontend of your website and inspect elements using Developer Tools (right-click > Inspect > Network tab).
    • Ensure that URLs for static assets such as images, JavaScript, and CSS are being served from https://s1.aptocdn.com/{domain}/.
  6. Purge All Caches:
    • To make sure the integration is complete, go to Performance > Dashboard and click Purge All Caches. This action clears the cache and forces W3 Total Cache to serve updated content through the CDN.

Troubleshooting Tips:

  • Assets Not Loading from CDN: Double-check the CDN URL in the CDN Configuration tab for any typos or formatting issues.
  • Mixed Content Warnings: Ensure the CDN URL uses HTTPS if your site runs on HTTPS to prevent mixed content issues.
  • Missing Files: If certain files aren’t being served from the CDN, verify that they are included in the File Types to Include section under the General Settings.
