Abstract
A caching management method includes embedding a notification request tag in a dummy file, uploading the dummy file to a cache server, recording a timestamp indicating a first point in time that the dummy file is uploaded to the cache server, receiving an eviction notification indicating a second point in time that the dummy file is evicted from the cache server, and calculating an eviction time indicating an amount of time taken for the dummy file to be evicted from the cache server. Transmission of the eviction notification is triggered in response to processing the notification request tag, and the dummy file is not retrieved from the cache server between the first point in time and the second point in time. The eviction time is equal to a difference between the first point in time and the second point in time.
