Abstract
A method for utilizing process identifiers to invalidate cached data is disclosed herein. The invention is a method for associating persistently stored data with an identifier of the process which created it, such that when the process that created the data is no longer present on the machine where the data is stored the data may be marked as invalid to prevent the use of “stale” data.
