Sorry for the very slow reply.

You want to write a small redirector for squid.
See these URLs:

http://wiki.squid-cache.org/Features/Redirectors
http://www.squid-cache.org/Doc/config/url_rewrite_program/

The former URL includes some simple example perl scripts.
A redirector reads URLs (actually a simple line containing a URL and a
few other fields) and returns modified URLs if needed. Squid then
fetches the modified URL instead of the requested URL.

The important thing with the redirector (aside from simple stuff like
just doing the right thing) is to always flush the output after writing
the response line (that is what the "$|=1" in the example perl scripts
arranges).

I would augument your redirector to actually check that the requisite
file exists in your private store of update files. If it does, issue the
redirect. If not, issue the "no change" response and log the missing
file so you can fetch missing updates as they are found.
