1、squid.conf配置如下：
http_port 10.15.0.2:3128
cache_mem 2048 MB 
cache_swap_low 90 
cache_swap_high 95
dns_nameservers 10.15.0.1
#内存中最大缓存的文件
maximum_object_size_in_memory 1024 KB
#不缓存超过4MB的文件
maximum_object_size 4096 KB
minimum_object_size 0 KB
#有DNS正反解所得到的IP存在缓存区的大小，这样可以加快解析速度
#ipcache_size 1024
#ipcache_low 90
#ipcache_high 95
#fqdncache_size 1024
#禁止缓存
hierarchy_stoplist -i ^https:\\ ?
hierarchy_stoplist cgi-bin ?
acl QUERY urlpath_regex cgi-bin \?
acl denyssl urlpath_regex -i ^https:\\
no_cache deny QUERY
no_cache deny denyssl
#上面几个就是说遇到URL中有包含cgi-bin和以https:\\开头的都不要缓存，
#asp、cgi、php等动态脚本也不要缓存，
# https://开通的不缓存是因为一般我们进行电子商务交易，
#例如银行付款等都是采用这个的，如果把信用卡号什么缓存那不是很危险。
