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

Benchmark

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.

If a customized solution is required, please contact LiteSpeed Technologies at This email address is being protected from spambots. You need JavaScript enabled to view it.

NOTICE: The rewrite rules created by this plugin must be copied to the Load Balancer.

 Does LiteSpeed Cache for Drupal work with OpenLiteSpeed?

Yes.

 Does LiteSpeed Cache for Drupal have a crawler?

No, not at this time.

 How can I install LiteSpeed Cache for Drupal?

LiteSpeed Cache for Drupal works right out of the box with default settings that are appropriate for most sites. Please refer to the steps from our How to Install LSCache for Drupal page.

 How can I check if LiteSpeed Cache is enabled?

You can check if LiteSpeed Cache (LSCache) is enabled by using the browser's developer tools. Check out our guide Check if LiteSpeed Cache is Enabled for a step-by-step tutorial.

GDPR Statement

LiteSpeed Technologies values your users’ privacy. Although our software does not directly collect any personally identifiable information from visitors to your site, LiteSpeed may still be considered a data processor, as user information may be temporarily cached and/or logged, as outlined in this document.

Servers

LiteSpeed Web Server, OpenLiteSpeed, LiteSpeed Web ADC, and related software may record IP addresses as a part of normal logging. An access log and an error log may record visitor IP addresses and URL visited. The logs are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. This logging may be turned off through configuration. It is up to individual server administrators to come up with their own schedule for removing such logs from the file system.

Cache Solutions

Our cache plugins potentially store a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules.

LSCache for WordPress

In addition to caching, our WordPress plugin has an Image Optimization feature. When optimization is requested, images are transmitted to a remote LiteSpeed server, processed, and then transmitted back for use on your site. LiteSpeed keeps copies of optimized images for 7 days (in case of network stability issues) and then permanently deletes them.

Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to our server so that we may better provide technical support.

Neither of these features collects any visitor data. Only server and site data is involved.

Support Services

Sometimes, when you request technical support, LiteSpeed may ask for login credentials to various areas of your site. You may refuse to share such credentials, however refusal may impact LiteSpeed’s ability to provide the requested support services.

Upon completion of a support ticket, LiteSpeed immediately deletes all login credentials you may have shared.

Any user data encountered by LiteSpeed is kept strictly confidential. We never provide your support ticket information to any third party without your explicit consent.
