Under this ruling, am I now responsible for my brother's or boss's or
co-workers cache?
This is by no means hypothetical. Some years ago, I was asked to
consult
on an incident that appeared to be the first instance in the wild of DNS
cache contamination. The symptom: someone using a laptop would
attempt to
go to a site, and instead got "interesting" pictures. (It could, of
course, have been a monkey-in-the-middle attack, per
http://www.ex-parrot.com/~pete/upside-down-ternet.html). The answer
was a
lot more mundane: the browser was confused about its own cache, and the
previous user of that laptop had engaged in recreational web surfing
from
some hotel room.
