I got the impression that the OP wanted the rewrite to work the other way 
around.

Squid sees http://192.168.1.1/www.google.com and  re-writes it to 
http://www.google.com

I got the impression that the OP wanted Squid to be listening on this address, 
doing the rewrites, and then fetching from standard origin servers.

Yes, that's what the OP wants Squid to handle, I think.
