  3. proxy的運作流程及好處 1.下載網頁速度加快 2.增加下載續傳支援 3.上網更安全

  4. Squid設定 /etc/squid/squid.conf 參數設定 http_port 3128 icp_port 3130 cache_mem 128MB cache_swap_low 75 cache_swap_high 90 acl all src 0.0.0.0/0.0.0.0 acl dicip src 192.168.25.0/24 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 http_access allow dicip http_access deny all
