Network Distributed Caches (“NDCs”) (50) permit accessing a named dataset stored at an NDC server terminator site (22) in response to a request submitted to an NDC client terminator site (24) by a client workstation (42). In accessing the dataset, the NDCs (50) form an NDC data conduit (62) that provides an active virtual circuit (“AVC”) from the NDC client site (24) through intermediate NDC sites (26B, 26A) to the NDC server site (22). Through the AVC provided by the conduit (62), the NDC sites (22, 26A and 26B) project an image of the requested portion of the named dataset into the NDC client site (24). The NDCs (50) maintain absolute consistency between the source dataset and its projections at all NDC client terminator sites (24, 204B and 206) at which client workstations access the dataset. Channels (116) in each NDC (50) accumulate profiling data from the requests to access the dataset for which they have been claimed. The NDCs (50) use the profile data stored in channels (116) to anticipate future requests.
