Joomla & LiteSpeed Cache

LiteSpeed Cache (LSCache) is a server-level page caching solution built into LiteSpeed Web Server. When used with Joomla, it can deliver significant performance gains with minimal configuration. The rules below let you control caching behaviour directly via your .htaccess file.

Where to add the rules

Open the .htaccess file in the document root of your Joomla site and add the rules immediately before this line:

## Begin - Joomla! core SEF Section.

The rewrite 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

• Replace domain.com and www.domain.com with your actual domain name.
• The cache TTL is set to 1 hour (3600 seconds). To change it, update the max-age value in the RewriteRule line - for example, max-age=86400 for 24 hours.
• The /administrator condition ensures the Joomla admin area is never cached.
