Cache your XenForo 1.x Site

The LiteSpeed Cache Add-on for XenForo 1.x is a PHP-based add-on that communicates with your installation of LiteSpeed Web Server and its built-in page cache, LSCache. Because LSCache is built directly into LSWS, overhead is reduced and caching can be done more efficiently than with other PHP-based caches. LSCXF1 also supports HTTPS, HTTP/2, and QUIC out-of-box with no extra configuration necessary.

LSCache for XenForo 2.x is also available.


› Server-Level Full-Page Cache for Guest Users

› Integrated into LSWS and Web ADC

› Supports HTTPS, HTTP/2 and QUIC

› Works with OpenLiteSpeed and LiteSpeed Enterprise

› Auto-Purge Related Content After Edits

Frequently Asked Questions

The LSCache Add-on for XenForo is simply an interface. It allows XenForo 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 XenForo Add-on could not function.


A licensed LSCache Module is required in order to use the free LSCache XenForo Add-on.

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.
