in response to a request for the content object information, determining if the requested content object information is stored
in a cache memory of a local node and retrieving the content object information from the cache memory of the local node; and
if the requested content object information is determined not to be stored in the cache memory of the local node:

likelihood that the other content object information will be requested meets or exceeds a factor;
requesting the content object information and the other content object information from a remote node;
receiving the requested content object information including the other content object information from the remote node; and
storing the received content object information including the other content object information in the cache memory of the
local node;
