我使用鱿鱼与adzap，它可能是鱿鱼/ adzap不caching一个particluar域如。 cnn.com
这是我的squid.conf文件

acl allow_domains dstdomain www.cnn.com always_direct allow allow_domains
我很惊讶， always_direct正在工作。 正如其他人所说，只影响caching层次结构，你似乎没有使用一个。
如果你想控制caching，使用正确的configuration选项是cache （或no_cache ，取决于你正在运行的是什么版本的squid）。
例如
Acl dontcache dstdomain .cnn.com Cache deny dontcache Cache allow all
Squid指令always_direct指出，对于指定的ACL，请始终直接连接到它们，而不要连接到上游caching。 许多过滤代理设置为上游caching，所以filter不必担心caching（它委托给Squid）。
你的例子
acl allow_domains dstdomain www.cnn.com always_direct allow allow_domains
定义了一个名为allow_domains的访问控制列表，并allow_domains添加了www.cnn.com。 （您可能还想将其改为.cnn.com以允许其他CNN网站，但不仅仅是具有该后缀的任何内容，例如“malwarecnn.com”。
然后，always_direct允许ACL_NAME告诉Squid忽略该域的转发器。
（如果你回答自己的问题，请回答，否则有人会为未来的读者添加更多的细节:)
always_direct用于指定始终应该由Squid转发到原始服务器的请求， 而不使用任何对等体 。 这与caching无关。 而不是always_direct，你必须使用类似下面的东西
acl bypass_caching dstdomain cnn.com cache deny bypass_caching
TAG：cache – 一个ACL元素列表，如果匹配，会导致请求不能被caching满足，并且回复不被caching。 换句话说，使用这个强制某些对象永远不会被caching 。 您必须使用单词“DENY”来指示不应caching的ACL名称。
