A system and method accelerates distribution of content of a global communications network such as the Internet (20). A central proxy server (12) transmits extracted data files over a communications medium to provide content filling of local proxy servers (17). The communications medium may be satellite transmission and may be conducted using IP multicast. The local proxy servers concurrently receive the data files from the communication medium at a high rate of speed and store the data files in attendant local cache databases (29). The local proxy servers utilize a localized heuristics scheme to determine whether to keep or discard the data. When a user requests Internet data, the user's request is first received by the local proxy server. If the requested data is present among the extracted data files, it is rapidly transmitted directly to the user from the local proxy server, if not present, a request is transmitted to the central proxy server. |
