Ok success I remembered that midgard has issues with using the local host and only 
works with fully qualified domain names. So I set up apache to to listen on port 8002 
and changed the live site to be on port 8002 and now I have the live site being 
servered through squid. Only for some reason squid just seems to be passing requests 
straight through so the database is getting hit anyway. Oh well back to the squid.conf 
file and trying to figure out how to optimise mysql.

Cheers
John
