The purge cache by custom cache key feature enables you to define a URL for purging. You can also configure elements like the Header, Cookie, and user attributes included in the user request such as device type, country/region, and language. The system then generates a cache key based on the specified custom cache key rules. This way, you can purge cache files precisely according to your custom cache keys rules.
Scenarios
The purge by URL feature is not applicable when you apply a custom cache key. Instead, you use the purge cache by custom cache key feature to remove the cache file for the specified URL defined in your custom cache key.
