Dispatched when a cache entry is invalidated, generally this occurs when the entry is determined to be untrusted while one or more outstanding load requests are active for a given cache entry. This mechanism allows any outstanding content requests to be reset due to the fact that the cache entry has been deemed 'unshareable'. Each content request notified then attempts instead re-requests the asset.
