Abstract
A method may include receiving, by a first computing system, a first request from a first client device to download content. The method may further include receiving, by the first computing system from a second computing system, first information. The first information may be indicative of a first version of the content that the first client device is authorized to download and a source from which the first version of the content can be downloaded. The method may also include determining, by the first computing system and based at least in part on the first information, that the first version of the content is already present on the first computing system. The method may additionally include sending, from the first computing system to the first client device, the first version of the content or second information, the second information indicative of the first version of the content.
