squid cache

[Brian May <bam@debian.org>]

Hello,

how do you get squid to *cache* data?

I tried using the following in my squid configuration:

refresh_pattern         \.deb$          43200   100%    43200 override-lastmod ignore-reload
refresh_pattern         Release$        720     100%    720 override-lastmod ignore-reload
refresh_pattern         Packages.gz$    720     100%    720 override-lastmod ignore-reload
refresh_pattern         Sources.gz$     720     100%    720 override-lastmod ignore-reload

however, I just did a "apt-get update" on one computer, and went
straight to another computer and typed in the same command (same
sources.list file), and now it has to re-download everything again.

arrrgghhh!

How do I stop this? Is there anyway I can find out what is going
wrong? This is no way to reduce my volume charge fees...

Sometimes it caches files, other times it doesn't. There doesn't seem
to be any pattern in size, or anything else I can think of (although
this instance, it is only caching the smaller Packages.gz files).

Thanks in advance.
