[Apt-proxy-users] cache cleaning: deleting obsolete files

[Micha <ear...@gm...>]

Hello,

i'm no more on the list (too less problems with AP :)
-> please 'reply to all'.

The cache here is about 3.6 GB, and unfortunately my i can't
give the cache more than 4GB total (seperate partition) without
rebuilding the whole partition table... I switched from debian testing 
to unstable, yesterday, and there's still stable + testing stuff in the cache.
Plus repositores for obsolete backends that i don't use anymore.
However, i can find files from 2005 in the cache, and more than
1 version anyway. For example,

openoffice.org_2.0.0-5_i386.deb
openoffice.org_2.0.2-1_i386.deb

mozilla-browser_1.7.12-1.1_i386.deb
mozilla-browser_1.7.12-1_i386.deb
mozilla-browser_1.7.8-1_i386.deb

mozilla-firefox_1.0.4-2_i386.deb
mozilla-firefox_1.0.6-5_i386.deb
mozilla-firefox_1.0.7-1_i386.deb

The latter, found in debian/pool/main/m/mozilla-firefox, 
is a good example for a related issue, that is, changing 
package names and/or classification. Debian unstable has firefox
version 1.5, which i can find now in debian/pool/main/f/firefox:

firefox_1.5.dfsg+1.5.0.1-4_i386.deb
mozilla-firefox_1.5.dfsg+1.5.0.1-4_all.deb

The question is, can i have AP 'clean up' all files that are older
than a specified time regardless of the number of versions ?
Can i modify the config temporarily to delete anything older than (today) 1 day, 
and that would leave me with 'sid' only ?

These are the related config settings:

min_refresh_delay = 1h
cleanup_freq = 1d
max_age = 1d
max_versions = 1
dynamic_backends = off

So, how can i have AP clear the old files ?
