Frequent questions

These are some of the questions we are asked most often.

Is the LiteSpeed Cache plugin for WordPress free?

Yes, LSCWP 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 lite speed server is required in order to use the caching tools of this plugin.

  1. LiteSpeed Web Server Enterprise with LSCache module (v5.0.10 +)
  2. OpenLiteSpeed (v1.4.17+)
  3. LiteSpeed WebADC (v2.0+)

Any single server or cluster that includes one of the LiteSpeed products listed above will work.

What is the difference between the LSCache module for LSWS (requires a license) and the LSCache plugin for WordPress (free)?

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

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

A licensed LSCache module is required to use the free LSCache plugin.

Does this plugin work in a clustered environment?

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

If you use another load balancer, the cache entries will only be stored on the backend nodes, not on the load balancer.

Purges will also not be synced between nodes, so this is not recommended.

If a custom solution is required, contact LiteSpeed Technologies at [email protected] (would DK's email actually go here?)

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

Does LiteSpeed Cache for WordPress work with OpenLiteSpeed?

Yes, it can work fine with OpenLiteSpeed, although some features (such as ESI) may not be supported. Any configuration change that requires modifying the .htaccess file will require a server restart.

Does it support WooCommerce?

Yes; however, for some WooCommerce themes the cart may not update correctly. Query this post blog, WooCommerce section, for a quick tutorial on how to detect this problem and fix it if necessary.

Are my images optimized?

Images are not automatically optimized, but if you want us to, we offer an Image Optimization feature. Find it in LiteSpeed Cache > Image Optimization.

Does LiteSpeed Cache for WordPress have a crawler?

Yes. The hosting provider must enable the tracker. Once enabled, the crawler can be configured to walk your site on a regular basis and re-cache pages that have expired from cache. Visitors are much less likely to find uncached content on a well-crawled site. Pages load fast and offer a positive user experience.

How to install LiteSpeed Cache for WordPress?

LiteSpeed Cache for WordPress works right out of the box with default settings that are appropriate for most sites. See the steps on our page How to install LSCWP.
