Abstract
A system and method for communicating a side effect of one data request, or other event, as part of a response to another data request or event. The side effect may include notification of the invalidation of cached data, from an upstream cache to a downstream cache. The upstream cache may store invalidation notifications as they are generated or received, and as responses to data requests are sent downstream, piggyback or merge one or more notifications with a response. This scheme avoids the need to open separate communication connections using specified invalidation accounts and passwords.
