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.
