I don't think caching the entire file is what  Robert's looking for. The
issue is that on any given day 80% of the file is likely to be unchanged
(assuming it contains approx. 5 days of data - only the newest day of
programs will be different). A squid setup is still going to download the
whole file each day, rather than just the 20% that's new.

Cheers,
Steve
