LSCache for WordPress
Highly-customizable and little to no configuration necessary makes LSCache plugins the ideal solution to speed up users’ web applications. The Smart Purge technology allows you to manage the cache with ease.
Features
- Faster page retrieval than uncached content.
- Powerful cache-management tools that are impossible for the other plugins to replicate.
- Tag-based smart purging of the cache.
- Ability to cache multiple versions of generated content based on user agent, geography, currency and more.
- Pages that would publicly be uncacheable may be cached privately.
- Caching can be extended to include logged-in users.
- Large sites with rarely-changing content can be cached longer while punching holes for more frequently-changing widgets.
- Entire pages need not be cached privately if a hole can be punched for a personalized greeting or a shopping cart.
- Facilitates the use of the WebP file format for even smaller image files.
- Individual images may be reverted back to their original formats if desired.
- Not reliant on external visitors to populate the cache.
- Minimizes the chances that a visitor will encounter uncached content
- Is smart enough to adjust its own level of resource consumption to minimize its impact on the server
- Can be configured separately. Enable only the minification functions you need.
- Shrinks the size of the source code, making it more efficient to transmit over networks.
- Can be configured separately. Enable only the combination functions you need.
- Reduces the number of requests made by the browser and potentially removes duplicate code, both of which translate to improvements in speed.
- Sends the included CSS and JavaScript files when index.html is requested.
- Reduces the number of requests necessary when loading a web page.
- Eliminates the need for a separate CDN plugin.

- Appeals to mobile visitors conscientious about the cost of bandwidth.

Frequently Asked Questions
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.
A LiteSpeed server is required in order to use the caching features of this plugin.
- LiteSpeed Web Server Enterprise with LSCache Module (v5.0.10+)
- OpenLiteSpeed (v1.4.17+)
- LiteSpeed Web ADC (v2.0+)
- QUIC.cloud
Any single server or cluster that includes one of the LiteSpeed products listed above will work.
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 Plugin for WordPress is simply an interface. It allows WordPress 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 Module, the Plugin could not function.
A licensed LSCache Module is required in order to use the free LSCache Plugin.
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 info@litespeedtech.com
NOTICE: The rewrite rules created by this plugin must be copied to the Load Balancer.
Yes it can work well with OpenLiteSpeed, although some features (such as ESI) may not be supported. Any setting changes that require modifying the .htaccess file will require a server restart.
In short, yes. However, for some woocommerce themes, the cart may not be updated correctly. Please see this blog post for a quick tutorial on how to detect this problem and fix it if necessary.
Images are not optimized automatically, but if you'd like to have it done we provide an Image-Optimization function. Find it at LiteSpeed Cache > Image Optimization.
Yes. The crawler must be enabled by your hosting provider. Once enabled, the crawler can be configured to traverse your site on a regular basis, and re-cache any pages that have expired from cache. Visitors are far less likely to encounter uncached content on a well-crawled site. Pages load fast and deliver a positive user experience.
LiteSpeed Cache for WordPress 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 LSCWP page.
