上面的-p后面根的是端口，根据自己具体的情况而定。如果是3128端口，就把上面的80换成3128就行了。另外一些常用的squidclient查询语句如下：

squidclient -p 80 mgr:info      #取得squid运行状态信息：
squidclient -p 80 mgr:mem     #取得squid内存使用情况：
squidclient -p 80 mgr:objects #取得squid已经缓存的列表,使用时要小心，可能会造成squid崩溃：
squidclient -p 80 mgr:diskd  #取得squid的磁盘使用情况：
squidclient -p 80 -m PURGE http://www.361way.com  #强制更新某个url,即清理某连接的squid
