DFS 10.1.0 - Data cache
Inspect the data cache. Here you see what has been cached for the different areas. You have the option to clear the cache and also send out an event to all CD servers to clear their data caches.
To invoke the event on the CD Server, you must locate the following file \App_Config\Include\damforsitecore\DFS.Connect.config. Open it and find the tag events. By default the event name publish:dfsClearCache:remote will be commented out. Remove the commenting to enable this custom event.
