Better Caching for Drupal

Modern versions of Drupal have built-in page caches: one for static content, and another for dynamic content and logged in users. Drupal's dynamic page cache essentially works as a PHP-based reverse proxy. This built-in proxy is acceptable if you have no other choice, but sites running on LiteSpeed Web Server or OpenLiteSpeed have a better option.

The LiteSpeed Cache Module for Drupal 8 and 9 is free and open source. It provides a sophisticated tag-based cache management system that serves both logged-in and non-logged-in users, resulting in better performance and a superior user experience.

Why Should You Use LiteSpeed Cache for Drupal?

Drupal's built-in dynamic page cache, can't compare to LiteSpeed Cache. LiteSpeed's server-based full-page cache does not need to invoke PHP, which means it is able to provide far superior performance and a better user experience.

  •  Server-Level Full-Page Cache
  •  Tag-Based Caching and Purge
  •  Much Better Than Built-in Cache
  •  Support for Drupal 8 and 9
  •  Set a long or short TTL as needed
  •  Integrated into LSWS and Web ADC


LiteSpeed Cache for Drupal handles more page requests, and results in a lower memory load and CPU load than any cache solutions on the market. This adds up to superior performance for your Drupal site!

Frequently Asked Questions

 Is the LiteSpeed Cache Module for Drupal free?

Yes, LSCache for Drupal will always be free and open source. That said, a LiteSpeed server is required, and there are fees associated with some LiteSpeed server editions.

 What server software is required for this plugin?

A LiteSpeed server is required in order to use this plugin.

  1. LiteSPeed Web Server Enterprise with LSCache Module (v5.2.2+)
  2. LiteSpeed WebADC (v2.1+)

Any single server or cluster including a LiteSpeed server will work.

 What is the difference between the LSCache Module for LSWS (requires a license) and the LSCache Module for Drupal (free)?

The LSCache Module is built into your licensed copy of LiteSpeed Web Server. When it comes to caching dynamic content, the LSCache Module does all of the work.

The LSCache Module for Drupal is simply an interface. It allows Drupal to instruct the server Module on what to cache, how long to cache it, and when to purge. And it allows the site owner to manage and configure the Module. Without the server Module, the Drupal Module could not function.

A licensed LSCache Module is required in order to use the free LSCache Drupal Module.

 Does this plugin work in a clustered environment?

The cache entries are stored at the LiteSpeed server level. The simplest solution is to use LiteSpeed WebADC, as the cache entries will be stored at that level.

If using another load balancer, the cache entries will only be stored at the backend nodes, not at the load balancer.

The purges will also not be synchronized across the nodes, so this is not recommended.
