squidclient是squid自带的一个小工具,一般用的最多的,就是-m purge URL了。 其实还有别的用法(看看help吧,不过这个慢慢来~~)先说一个大全式的用法(其他的具体用法,大不了用这里rep出来好了):squidclient -p 80 mgr:info,显示如下:

另外,还有一个squidclient -p 80 mgr:objects,号称是慎用的大杀器,能够列出缓存文件列表——问题是:我找了个新开squid的测试机一试,发现列表显示内容是这个样子的: KEY 29E6623108A3E8A64DBBD016AB239AEA STORE_OK NOT_IN_MEMORY SWAPOUT_DONE PING_NONE CACHABLE,DISPATCHED,VALIDATED LV:1258460822 LU:1258461412 LM:1258460823 EX:1260950400 0 locks, 0 clients, 1 refs Swap Dir 0, File 0X000412 上头是32位MD5值么?谁看的懂呢……
