there's a patch that has to detect if the requested file is already in the
cache, even if fetched from different site:
http://devel.squid-cache.org/projects.html#dsa

However it's for squid-2.4 only :(

yes. I know it's not good but this problem really lies on the server side.
I think servers shouldn't provide two different virtualhosts with the same
data, but better send redirects from alternative virtualhost to the main
one. Bad that e.g. apache does not do that automatically for server aliases.

servers should take care of it first (vhost aliases), then a protocol should
probably count with it (expand Content-Location to virtualhost too?)
