Ok, just for reference: I dig'ed the sites hosting those iso files and
set up some iptables rules in the INPUT chain to block tcp/80 traffic
coming from them, plus some OUPUT chain rules to block outgoing traffic
as well.
Within seconds the wan traffic decreased even though I did not put those
rules on the gateway, only on the squid host.
After some time squid dropped the connection, probably due to a timeout,
and I deleted the blocking rules.

This way I've been able to "cancel" ongoing downloads without restarting
squid.
