AEM Dispatcher Caching Flush Strategies
When caching is implemented for your website, it's essential to clear the dispatcher cache after publishing pages
to ensure the most recent content is displayed to end users. To reflect changes made by authors, we need to configure Replication
Agent on Author instance to push changes to the Publish instance and Dispatcher Flush Agent on Publisher instance to invalidate
the Dispatcher cache. Once the cache is invalidated, next request will be served from the publisher, and the response will be added
to the cache; subsequent requests will be served from the cache without interacting with the publisher.
