[squid-users] Timeout on search engines

I have configured squid 3, I have a parent proxy that must be used and I have set the connection to it in my squid.conf file (provided below). I can browse the internet fine and I can get to internet search engines fine but when I do a search on a search engine (like www.google.com) the page will timeout. I have provided my squid.conf file below
