PyroCMS 2.x can serve static assets through a Gcore CDN resource by setting a custom domain in the admin panel’s Integration settings. Create a CDN resource before starting the integration. Configure its custom domain with a valid CNAME record and an active SSL certificate.

​
PyroCMS 2.x

This procedure assumes a PyroCMS 2.x installation with the standard local static-asset layout and an Integration CDN field in the admin panel.
Back up site files and the database before making changes.
1

Locate the custom domain

In the Gcore Customer Portal, find the custom domain on the CDN resources page.
2

Verify origin access

Identify a known static asset used by the site. Request the same path directly from the protocol and hostname configured as the CDN origin:
Continue only after the origin returns the expected file without a 403 or 404 response.
3

Open the Integration settings

Log in to the PyroCMS admin panel and navigate to Settings > Integration.
4

Set the CDN domain

Enter the custom domain as a hostname without the protocol or trailing slash: cdn.site.com.This setting changes URLs generated through the PyroCMS Asset library. Update hardcoded asset URLs in templates separately because the Integration setting doesn’t rewrite them.
5

Apply the changes

Click Save.
6

Verify asset delivery

Open the browser’s developer tools by pressing F12, select the Network tab, and refresh the page. Asset-library-generated URLs should load from the custom domain instead of the origin domain.
