Feature request: Created(key)

[jordanrobot]

Please consider adding a public property that returns the creation date of a cached item by key. This would simplify use cases where caches are managed relative to external time-based objects.

E.g. consider a network file enumeration that is cached for performance purposes. Using this new property you could trigger a rescan and cache when the folder modified date is newer than the cache's created date.

if (created < folderModifiedDate)
  {
    //FileEnumeration of network location
    //Update cache
  }
