我这里有一个三节点的 apache mod_proxy 负载平衡集群。现在我想启用 mod_cache 以将更多的负载从后端传输到前端。
这就是我的缓存配置：
<IfModule mod_cache.c>
<IfModule mod_disk_cache.c>
CacheDefaultExpire 3600
CacheEnable disk https://
CacheEnable disk /
CacheRoot "/mnt/ram/"
CacheDirLevels 2
CacheDirLength 1
CacheMaxFileSize 1000000
CacheMinFileSize 1
CacheIgnoreCacheControl On
CacheIgnoreNoLastMod On
CacheIgnoreQueryString Off
CacheIgnoreHeaders None
CacheLastModifiedFactor 0.1
CacheDefaultExpire 3600
CacheMaxExpire 86400
CacheStoreNoStore On
CacheStorePrivate On
</IfModule>
加载Apache模块：

所以问题是，对网站的任何请求也会发送到后端，因此没有性能优化。
有没有办法可以用 mod_cache 来解决这个问题？
Apache版本：2.4.10（Debian8）后端：Typo3 网站。
