Abstract

Re-Fetching Flush Agent
With regular flush agent, the agent flush the cache and the flushed content would only be retrieved from the publisher again after first time requested. This will create issue if the multiple parallel requests hit the dispatcher after flush as the new page is not yet cached in the dispatcher.
