Is it harmful to have "cache deny !to_ubuntu_mirrors" turned on by default? If that was OK, you could do something like
cache deny !to_ubuntu_mirrors
# Comment the next line and uncomment the one after it to allow but not
# cache domains not listed in the mirrors file
http_access deny !to_ubuntu_mirrors
#http_access allow !to_ubuntu_mirrors
which would simplify the changes an admin would have to make.
