网站前端nginx负载均衡，用户访问静态页面proxy_pass到squid服务器上
squid服务器反向代理加速并配置了多台nginx虚拟主机# (Format: external IP : port)
http_port 3128
http_port 172.16.0.120:80 vhost
http_port 111.111.111.111:80 vhost
cache_peer 172.16.0.120 parent 81 0 no-query originserver  no-digest name=a
cache_peer 172.16.0.120 parent 82 0 no-query originserver  no-digest name=b
cache_peer_domain a www.a.com
cache_peer_domain b www.b.com
