You can use Purge Cache to invalidate or delete cached content in a rapid and predictable manner. This improves offload and performance for fresh, event-driven content. Before Purge Cache, customers avoided caching event driven content, or had to cache it for very short TTLs. This content includes news stories, inventory or pricing data, and often API traffic.

How to use Purge Cache
