Abstract
A content server farm in a host network may be configured to receive a message indicating that content is to be downloaded to a content consumer device in the host network different from a partner network. A first copy of the content is stored at an originating content provider device in the partner network. A path for downloading the first copy of the content from the originating content provider device in the partner network to the content consumer device in the host network includes peering points that connect the host network to the partner network. The content server farm may determine whether a second copy of the content is cached at the content server farm in the host network, acquire the content when the second copy of the content is not cached at the content server farm in the host network, cache the content as the second copy at one or more locations in the content server farm in the host network, and generate indices that correspond to the second copy of the content and the locations at which the second copy of the content is stored.
