A recompression server (20) that automatically decompresses selected pre-compressed data streams and recompresses the decompressed data to a greater degree than the original pre-compressed data. In one embodiment, the recompression server (20) determines from a request whether a requested file is pre-compressed. In another embodiment, the recompression server (20) determines from a retrieved requested file's name or attributes whether the file is pre-compressed. Optionally, the recompression server (20) may cache frequently requested files in re-compressed form to further optimize the bandwidth of a wide area network (8). Such caching can be done on-line or off-line
