Content paths can either be invalidated or flushed from the AEM
Dispatcher cache.AEM Dispatcher behavior - invalidate performs a cache
invalidation, similar to when content is activated from author to
publish (CQ-Action: Activate, CQ-Action: Deactivate) flush performs a
cache deletion (CQ-Action: Delete).In general, the use of the invalidate
action is preferable but there may be cases where flushing is required,
especially when using AEM HTML Client Libraries.
