pkg and HTTP caches

[Victor Sudakov]

Dear Colleagues,

While accessing the FreeBSD package database via a corporate HTTP
proxy, I have noticed that all fetches are cache misses (see below). I
think this is because of the "Cache-Control: max-age=0" directive.

While I can probably understand the reason to never cache repository
metadata, I completely fail to see what the problem is with caching
packages proper. Taking into account the amount of packages I install
and upgrade on several identical systems, caching them would
sufficiently save bandwidth.

Any comments please?
