Joomla & LiteSpeed Cache

LSCache, similar to Varnish cache, is a simpler and more efficient page caching solution built-in to LiteSpeed Web Server. When used in conjunction with Joomla, you can expect significant performance gains with a quick and easy setup. Cache management is also made significantly easier and more flexible. While the LiteSpeed cache plugin for Joomla is still in development, rewrite rules can still be used to customize LSCache's behavior.

Where should I add the rules?

Rewrite rules should be added to your .htaccess file, located in the document root of your website, right before the following line:

## Begin - Joomla! core SEF Section.

Which are the rules?

########## Begin - Litespeed cache 
<IfModule LiteSpeed> 
  RewriteEngine On 
  CacheDisable public / 
  RewriteCond %{REQUEST_METHOD} ^HEAD|GET$
  RewriteCond %{HTTP_HOST} ^domain.com [NC] [OR]
  RewriteCond %{HTTP_HOST} ^www.domain.com [NC] 
  RewriteCond %{ORG_REQ_URI} !/administrator 
  RewriteRule .* - [E=Cache-Control:max-age=3600] 
</IfModule>
########## End - Litespeed cache

Notes

You need to replace your domain.com and www.domain.com with the domain you use for Joomla
Per the rules above the cache TTL is set to 1 hour and it's configured in seconds ( 1 hour = 3600 seconds). If you want to change the cache TTL change the max-age value from the RewriteRule
