A straightforward approach would be to URL encode the socket name and use
that as the host name, e.g. http://%2Ftmp%2Fserver/resource would use the
UNIX socket /tmp/server. This should be unambiguous as / is illegal in a host
name. It looks ugly though, and would force a %2F to be added to all socket
names even when it wouldn't otherwise be needed, e.g.
http://.%2Fserver/resource I haven't check to see if this would play
well with IDN and whether adding a .%2F is allowed on all platforms.
