Edge Caching for Web Services

Serve static content from a global edge cache for faster delivery.

Render provides edge caching for static assets (documents, images, etc.) served by paid web services. With edge caching enabled, you can speed up response times and reduce load on your web service:

Edge caching is powered by the same global CDN as Render static sites.
