Purge is a tool for refreshing specific cached objects or removing all stale content across the Akamai edge network. You can refresh your content on edge servers based on a few categories. The purge requests are propagated through the Akamai edge network, using either the invalidate or delete purge methods.
Purge and TTL work together
Remember that the purge mechanisms shouldn't substitute the time-to-live (TTL) settings in your cache configuration or in response headers, which better maximize system and content delivery performance.
