Netlify has introduced `Netlify-Cache-ID`, a new feature that allows developers to label their cached content with an ID, providing full control over caching while maintaining atomic deploys. This feature enables the creation of cache tags and provides a way to invalidate objects with specific IDs across all Netlify Edge networks, ensuring consistency and performance. With `Netlify-Cache-ID`, developers can customize how long their objects stay cached, still benefiting from the Cache-Tags feature for added flexibility.
