LSCache for Drupal

Drupal 8 is significantly changed from Drupal 7. They have converted from procedural programming to object-oriented programming. Drupal 8 has a built-in page cache (for static content) and a dynamic page cache for logged in users. The latter basically works as a reverse proxy written in PHP. The built-in proxy is good if you have no other options, however, with the LiteSpeed Cache plugin you will see a great improvement in performance for your Drupal 8 site.

This version of LiteSpeed Cache requires Drupal 8.xx or later and LiteSpeed Web Server (LSWS) 5.2.3 or later. See our Guide for Installing Drupal on a Standalone LiteSpeed Web Server.

Download the LiteSpeed Cache module to your local computer from our GitHub repository.

Create .htaccess if it doesn't exist, and add the following:

<IfModule LiteSpeed>
CacheLookup on

Once you have downloaded the plugin, you can install it by visiting

Using the browse button you can upload the plugin you just downloaded and start the installation. Once installed, enable the plugin by going to:

  1. Use the search box to search for a module.
  2. Check the checkbox next to LiteSpeed Cache.
  3. Click Install.

This step is optional. Once the plugin is activated, your cache is already up and running, but on the configuration screen, you can customize few settings.

Go to

Clear Cache

Clear this site

This option only clears the current Drupal installation. This helps if you have multiple Drupal installations on the same virtual host.

Clear all

This button clears the entire LiteSpeed cache for this virtual host. This includes any other web apps using LSCache (WordPress, XenForo, etc.) on this vhost.


If turned on, LiteSpeed Cache will emit extra headers for testing while developing or deploying.


OpenLiteSpeed doesn't support ESI, although it does no harm to keep it turned on.

Max Age Private
