Zinn® Cache 插件
什么是 Zinn® Cache、免费版和 Pro 版、由哪个缓存为您的页面提供服务（LiteSpeed、nginx、Varnish、Apache、Cloudflare 或其自身缓存）及其指南。
Page cache, Redis object cache and purging for nginx, Varnish, Apache, LiteSpeed and Cloudflare — updates refresh pages gradually, never all at once.
Free and Pro
Zinn® Cache is free and complete, from WordPress.org, with no licence key. Zinn® Cache Pro is an optional paid add-on that installs on top of it; prices are in Zinn® WordPress plugin prices.
Which cache serves your pages
On a LiteSpeed server Zinn® Cache drives the server's own page cache. When nginx, Varnish or Apache already caches pages in front of WordPress, it does not add a second page cache behind it: it purges changed pages there (and on Cloudflare, when that is switched on). Anywhere else it stores each page as a file and serves it before WordPress loads. Updates and plugin activations refresh the site a batch a minute instead of emptying the cache at once.
