Well, it would help to know what protocol you were useing... http/ftp
might be redirected like that but not say rsync.

Normally though a proxy *unless borked* would check the datestamps before
providing a chaches file, don't cache files over a couble meg, and *would
not* have enough of a debian mirror in cache to cause this. (Most high
volume cacheing system don't even bother caching files over 256k or so).

In any event, there is nothing like this in place at ACS Internet.
