Ah, well in the effect the http_proxy variable is not special to
apt-get , almost all (I don't recall an exception) unix command line
programs in different distributions obey this variable, also many
programming language libraries. Examples are yum, wget, java ...
So if you set these two variables in a general shell option file, you
should be done for most cases.

But there is also a different solution to this problem. You can use
squid to do transparent proxying, that is, intercept outgoing requests
on port 80 (instead of 8080, 3128 etc) and redirect them to the origin
servers. With a setup in this way, all applications work without proxy
settings as they never know they are talking to a proxy. Instructions
for setup can be found in the squid wiki and in many howtos out there.

But beware! This setup has other disadvantages. Before deploying such a
setup - in fact, before deploying any proxy setup in a production
enviroment - you should thoroughly test this with an environment where
failures are not critical.
