Abstract: Transaction activity of a cache maintaining content may be monitored to determine periods of transaction activity below a first threshold amount of transactions. A period of anticipated transaction activity above a second threshold amount of transactions may be determined. A period of anticipated transaction activity below the first threshold may be selected based upon the monitored periods of transaction activity below the first threshold and the determined period of anticipated transaction activity above the second threshold. Content then may be evicted from the cache during the selected period of anticipated transaction activity.

Abstract: Aspects of the disclosure relate to validation of a request for an asset based on information in the request. Validation of the request can be processed by a network node in a network repository that contains the asset. In one aspect, validation of the request can comprise determining if the request is legitimate based at least on processing at least a portion of the information in the request. In response to a legitimate request, the network node can process the request and, as a result, a data object associated with the asset can be supplied to a device originating the request. In the alternative, the network node can yield an exception.
