LSCache plugin for Joomla

LiteSpeed Cache for Joomla

LiteSpeed Cache for Joomla is a high performance, low cost, user friendly cache plugin. It will tremendously speed up your site, and reduce server load with minimal management efforts.

For most Joomla sites, the default settings work well. Very few options need to be changed.

For advanced Joomla sites such as E-Commerce sites, the advanced ESI feature and cache options for logged-in users will help run your complex business site like a static file site. It will tremendously improve your customer experience.

The smart auto-purge feature will minimize your management needs. No more worrying about cache sync problems. LSCache will detect that you changed an article, you changed a menu setting, or you changed a module setting. Then, it will automatically purge related pages. So, you can set a longer cache expiration time to improve visitor experience, confident that the cache will be purged when the relevant content or settings change.

Some components and some pages may not work well with cache. We can set flexible exclude rules for those components and pages. We have both a simple easy way and a powerful complex way (supporting regular expressions).

We'll keep on improving this cache plugin. Your opinion and feedback is important to us!
