Last night I came up with another way of dealing with "cache unfriendly"

The cache could keep track of what sort of hit rates it gets for each
server hostname. In situations where bandwidth is scarce, the low-hit-rate
sites could be given lower priority or "quality of service."

So as a cache administrator, you're not in violation of the HTTP protocol.
The users behind your cache still get the objects from the unfriendly sites,
but perhaps with considerable delay. In situations where bandwidth is
relatively plentiful the priority/QOS effects shouldn't be noticable.
