How to activate LSCache

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

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.

Please follow the official guideopen in new window on how to enable LSCache.

Once you've set up your web server and configured the cache root and cache policies, you're ready to install a plugin. LSCache pluginsopen in new window are available for many popular web applications. The plugins allow you to configure and manage your LiteSpeed server's cache simply and easily, through the application's own familiar interface.
