Interface IDeliveryApiOutputCacheEvictionProvider
Provides additional cache tags to evict from the Delivery API output cache when content changes.
Namespace: Umbraco.Cms.Core.Cache
Assembly: Umbraco.Core.dll
Syntax
public interface IDeliveryApiOutputCacheEvictionProviderRemarks
Multiple implementations can be registered. The eviction handler iterates all providers to collect additional tags to evict beyond the built-in content key tag.
Works as a pair with IDeliveryApiOutputCacheTagProvider: the tag provider adds custom tags when caching a response, and this provider maps content changes back to those tags at eviction time.
