What is LSCache?

LiteSpeed Cache (LSCache) is a built-in, high-performance dynamic content acceleration feature of the LiteSpeed Web Server.

LSCache is included (free) in Free Starter, Site Owner, and Web Host licenses (v5.3 and above).

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 LiteSpeed Web Server.

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.

LSCache is the solution for a faster, more enjoyable user experience.

What is LSCache for WordPress?

LiteSpeed Cache for WordPress (LSCWP) is a PHP-based plugin that provides page caching and other site optimization features, which deliver superior performance to your WordPress site.

The LSCache plugin communicates with LiteSpeed Web Server's LSCache module to provide more efficient and intelligent caching than other PHP-based cache plugins.

If you are a System Administrator for a shared hosting server and are currently using WHM/cPanel, you may find the LiteSpeed Cache for WordPress Management section within the LiteSpeed WHM Plugin to be a big time saver. It allows you to enable cache for all of your WordPress installations with one-click.


Before you can use the LSCache for WordPress plugin, you must first execute a few common cache setup steps.

Obtain a LiteSpeed Web Server

You will need one of the following LiteSpeed server products in order to use LSCache:


OpenLiteSpeed does not support ESI. If you wish to use ESI, you will need LiteSpeed Enterprise.

Configure Cache Root

For more information, see LiteSpeed Web Cache Common Installation Guide.

Install, Configure and Use the Plugin

Once you've set up your web server and configured the cache root and cache policies, you're ready to install the WordPress plugin. The LSCache will allow you to configure and manage your LiteSpeed server's cache simply and easily, through the WordPress's own familiar interface.

Start with Installation and follow the documentation menu to configure and use the plugin.
