CDN

Configure a Content Delivery Network to accelerate and protect your website

A Content Delivery Network (CDN) places copies of your static assets — images, stylesheets, scripts, fonts, documents — on edge servers distributed around the world. When a visitor requests your page, those assets are served from the nearest edge location instead of from the origin server. The result is faster load times, lower server load, and a better experience for your users, no matter where they are.

Two separate CDN hosts can be configured:

• CDN Host — used for static files under /Files/ (stylesheets, scripts, images, documents, etc.)
• CDN Host (GetImage) — used specifically for image transformation requests via /Admin/Public/GetImage.ashx

You can use the same URL for both, or separate them if your setup requires it.

Basic CDN configuration

To set up CDN for a DynamicWeb solution, first navigate to Settings > System > Web & HTTP > CDN.

1. Check Enable img and script src replacement
2. In CDN Host, enter your CDN endpoint URL — e.g. https://mysite.cdn.dynamicweb.cloud
3. In CDN Host (GetImage), enter the same URL — e.g. https://mysite.cdn.dynamicweb.cloud
4. Click Save

This is a global setting — it applies to all websites on the solution.

Note

The CDN host URL must start with https://. If the URL does not have a valid protocol prefix, CDN replacement will be silently disabled.

You can read a more in-depth explanation of how CDN works inside DynamicWeb in the implementer CDN Setup guide.

Verifying it works

After enabling CDN:

1. Open your website in a browser
2. Right-click an image or stylesheet reference and choose Inspect
3. Confirm that the src or href attribute now starts with your CDN host — e.g. https://mysite.cdn.dynamicweb.cloud/Files/...
4. In the browser Network tab, verify that static assets are served from the CDN host
