Cache your XenForo Site
The LiteSpeed Cache Add-on for XenForo (LSCXF) 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 cache. LSCXF also supports HTTPS, HTTP/2, and HTTP/3 out-of-box with no extra configuration necessary.
Why Should You Use LiteSpeed Cache for XenForo?
LiteSpeed's XenForo cache add-on allows you to significantly speed up your forum pages and keep your visitors' attention. Nobody wants to wait more than a few seconds for pages to load. With LSCache, your guests won't have to.
- Server-Level Full-Page Cache for Guest Users
- Supports HTTPS, HTTP/2 and HTTP/3
- Integrated into LSWS and Web ADC
- Works with OpenLiteSpeed and LiteSpeed Enterprise
How it Works
The LiteSpeed Cache Add-on supports XenForo 2.x. It caches dynamic content as static HTML for guest users. Using rewrite rules, content is cached for 5 minutes at a time. On a busy forum, this is enough to reduce server load significantly.
Frequently Asked Questions
Is the LiteSpeed Cache Add-on for XenForo free?
Yes, LSCXF 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?
One of the following LiteSpeed servers is required in order to use this plugin:
- LiteSpeed Web Server Enterprise
- LiteSpeed WebADC
Any single server or cluster that includes a modern version of a LiteSpeed server will work.
What is the difference between the LSCache Module for LSWS (requires a license) and the LSCache Add-on for XenForo (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 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.
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.
