Introduction

What is LSCache?

LiteSpeed Cache (LSCache) is a built-in, high-performance dynamic content acceleration feature of LiteSpeed server products.

LSCache accelerates dynamic content (not just PHP pages), with features very similar to those in Apache mod_cache, using an efficient, highly customizable, native implementation within the LiteSpeed server, which greatly reduces page load time and server load.

LSCache eliminates the extra reverse-proxy layer(s) required by add-on cache packages (such as Varnish), providing faster, more efficient handling of static content in addition to its stellar handling of dynamic content.

Why Use a Plugin?

The LiteSpeed Cache Engine can be controlled through rewrite rules in the .htaccess of a web app's document root. So what do you gain by using an LSCache plugin?

An LSCache plugin bridges the knowledge gap between a web app and the Cache Engine.

Put another way: web apps have rules about what content may be cached, for how long it may be cached, and what events would cause a cache object to become stale. LSCache plugins are a way of communicating these web app rules to the Cache Engine. LSCache plugins allow you to manage the cache in such a way that more objects may be stored for a longer period, and with unparallelled accuracy.

Available Plugins

LSCache plugins are available for many popular CMS:

No Plugin

If there is no plugin for your CMS, you can try your hand at writing one, or you can control LSCache with rewrite rules.
