When an ATG application modifies an item that uses distributed TCP caching, the following occurs:
When the local repository item cache is updated, the repository looks up the specified item descriptor in the
das_gsa_subscribertable, and determines whether other ATG instances define this item descriptor.If the item descriptor is found, the event server connects to the other event servers identified in
das_gsa_subscriber.An invalidation event is sent to the target event servers with the pertinent information: event type, item descriptor, and repository ID.
The receiving repositories invalidate caches for that item descriptor.
