The Cache modules are designed to assist a developer in persisting data for a specified period of time. Often, these modules are used in web applications to store data locally to save repeated and redundant expensive calls to remote machines or databases. People have also been known to use Cache::Cache for its straightforward interface in sharing data between runs of an application or invocations of a CGI-style script, or simply as an easy to use abstraction of the filesystem or shared memory.
