How to Connect a CMS to a CDN
IntermediateQuick Answer
TL;DR
Connecting a CMS to a CDN (Content Delivery Network) caches your content at edge locations worldwide, reducing latency for visitors regardless of their location. For headless CMS setups, the CDN sits in front of your front-end application, caching rendered pages and static assets. CMS webhooks trigger cache invalidation when content changes. Some CMS platforms include a built-in CDN for API responses; the front-end CDN is typically provided by your hosting platform.
Key Takeaways
- A CDN caches content at edge nodes globally, reducing server load and improving page load times.
- Headless CMS setups involve two CDN layers: one for the CMS API and one for the front-end application.
- Webhooks are the standard mechanism for triggering cache invalidation when content is updated.
- Cache-Control headers and TTL values determine how long content stays cached before revalidation.
