Looks like a nice solution, and we might try something like that to 
reach Chinese users.

Did you notice any ill effects of Bug 7 
(http://www.squid-cache.org/bugs/show_bug.cgi?id=7)? This bug makes 
Squid deliver resources with expiration times in the past, thus causing 
the clients to revalidate the resources every time they are used.
