kangle的访问logs目录下日志access.log文件缓命中率讲解，回源标识代号数据参考 参数分析

UA后方的代号数据仅供参考，我也无法完全理解是什么意思，CLT0代表是命中缓存，中间加了个V，CVLT0代表缓存强制做更新验证
应该都是英文省略字面意思，有兴趣做kangle日志分析或者动态感知系统的可以看看研究下。

可以用类似命令在ssh上实时滚动分析

1. tail -f /vhs/kangle/var/access.log | grep 117.183.0.214

复制代码

kangle反代CDN节点
从上到下分别为
1.首次浏览器打开
2.f5刷新，与反代服务器匹配文件无变动，返回304状态继续命中缓存
3.通过无痕模式打开
4.ctrl+f5刷新

kangle源站主机服务器
1.浏览器打开后首次回源
2.收到ctrl+f5后的回源，回显状态为304，验证文件无改动，继续命中缓存
