Abstract
According to one embodiment, a processor of a cache server delivers content acquired from an origin server to a client, using a storage device as a cache of the contents. When an error occurs in reading the content from the storage device, the processor determines whether or not to recover the content based on a recovery amount of a delivery capability of the cache server as a result of recovering the content and a cost of writing data to the storage device associated with recovery of the content. When determined to recover the content, the processor selects a content recovery method based on a first remaining retention period during which the content should be retained and a second remaining retention period until the content is to be erased from the storage device.
