#on 80 port load default site content
http_port 80 vhost defaultsite=192.168.10.23

#on 443 SSL port load default site content and using the given cert and key
https_port 443 defaultsite=192.168.10.23 cert=/etc/squid/server.crt key=/etc/squid/server.key

#cache the given IP content on port 80 and pass the HTTP auth info
cache_peer 192.168.10.23 parent 80 0 no-query originserver login=PASS
