The processing of the cache_host_domain lines is 'any match will do' (I
believe).
 
Hence, something like 123.com will match !.net, and france.frenet.fr will
be queried. The use.freenet.fr line will match any domain other than .fr
(as 123.xyz passes !.fr).

In effect, the first line matches any site.
The second anything but .fr

Not sure if the options here override the proxy-only option. You didn't
specify your requirements for storing local copies of retrieved data. What
you could(should?) do is use the sibling option for your main cache_host
lines, and override that here.

Set the timeout slightly higher if you're getting timeouts before the usa
host responds. Check the logs for this.
