因此它看起来记录了我所做的事情，还记录了程序下载了哪些文件
http://audaupdate.audatex.cz/MASTER_APP/FULL/MODEL/GRAPHIC/0000/GRA/0JD050/0JD050.GFF.ZIP - DIRECT/93.189.233.60 application/x-zip-compressed
无论如何，当我尝试再次下载同一个文件时，它会再次从原始网络服务器下载，而不是从缓存中下载。当我尝试观看某些视频或任何东西时，它总是在下载，从不从缓存中提供。也添加我的配置。有人能告诉我哪里可能存在问题吗？
清理后的配置如下：

答案1
Squid 无法保留来自 YouTube 等 CDN 或带有“?”字符的 URL 的对象。要缓存来自 CDN URL 的视频、图像等...您应该使用可以为您完成工作的插件。您可以尝试使用 SquidVideoBooster 来处理 600 多个网站，包括 YouTube、DailyMotion、NetFlix 等...
关联：https://sourceforge.net/projects/squidvideosbooster/ 兼容 Squid 2.7、3.4 和 3.5。
下载此插件并测试，您将看到它是否满足您的需求；o）
