Drupal: StackPath CDN Setup Guide

The SecureCDN module for Drupal alters URLs so static content loads from CDN servers instead of the origin server. After completing this tutorial, static content will be delivered from StackPath CDN.

This tutorial assumes a site is created


The CDN module for Drupal provides two modes: Origin Pull and File Conveyor. For setting up Drupal to use StackPath CDN, use Origin Pull. This mode is used as a domain name rewriting tool.

  1. Log in to the Drupal admin panel. Select Modules, then select Install New Module.

  2. In the Install from a URL box, enter the CDN Module URL:

  5. Replace this example URL with the CDN URL for your site.

  6. Click Save Configuration.
