In 2.0 quick_abort is about the only option you can tune to stop Squid
from using more incoming bandwidth than sent to the clients.
Unfortunately the current support for range requests may sometimes use a
bit more bandwidth that sent to the client and there is no options for
tuning this in 2.0. Squid 2.1 has some first attempts on limiting
bandwidth overuse on Range requests but it is far from perfect.

Incoming and outgoing in Squid 2 is quite loosly coupled with the cache
in between (in theory it is like this anyway.. there are some
dependencies).
