[squid-users] Squid problems with Windows Update

Yesterday, Microsoft announced a bunch of new bug fixes, which nearly
every Windows machine on the Net is eagerly downloading. Unfortunately, a
client of mine is having problems with a transparent Squid proxy with
Windows machines behind it. Apparently, Windows Update fetches updates in
chunks, about 2K at a time. (It is not clear whether this is done as
subranges of the file or as identical queries which produce different
results; I don't see any "@" signs in the URLs in the cache log, though.)
In any case, each time a client requests a 2K chunk, the Squid proxy is
re-fetching an entire file that's 2 MB or larger from a parent cache.
Needless to say, this is completely killing their bandwidth. Have others
seen this behavior? Is there a known fix?
