A caching proxy would be default look first into a cache of my choosing?
Of course sometime the local cache contains debs of the same version as
another source....so one might want to pin them higher....this would answer
one of your questions of why I might want to do this...
One of the difficulties I have noticed is that even though I have a package
that has a higher version than what's in the stable debian archive I don't
get it to download without having to say
apt-get -t unstable package....
NOTE. I downloaded the package from the unstable archive and
stuffed into my local cache.... and yet I couldn't get it to arrive
(most of the other packages didn't have this problem. I'm beginning
to think that some of the dependencies were from unstable and because
they're weren't available it wasn't installed....apt didn't say anything
specific about this....most other packages I got from unstable I built
on pure woody system before putting them into the local cache...and
these work... or packages that weren't available in debian/stable...
Some speculation on my part...

Not very good frankly and the apt-howto is a little better.
