Netlify has made significant improvements to its edge caching features, enhancing the platform's ability to create dynamic digital experiences. New additions include fine-grained cache control headers, Cache Tag support for selective content invalidation, and Netlify-Vary for caching dynamic content based on request variations. Additionally, a new HTTP response header called 'Cache-Status' offers insights into the caching process. This information can be used in conjunction with synthetic tests and Real User Monitoring (RUM) to better understand site performance and cache status.
