The LiteSpeedCache plugin is a MediaWiki extension for MediaWiki sites running on a LiteSpeed webserver. Enable its LSCache feature to speed up page loading, reduce response time, and tremendously reduce server load for MediaWiki sites.

See for more information.


MediaWiki is a free software open source wiki package written in PHP, originally for use on Wikipedia (the free encyclopedia). It is a feature-rich wiki implementation, that uses PHP to process and display data stored in its MySQL database. It is a fairly popular wiki application on the web.


This version of LiteSpeedCache requires MediaWiki 1.25 or later and LiteSpeed Web Server (LSWS) 5.2.3 or later.



Unzip the downloaded file with:



1. Create .htaccess if it doesn't exist, and add the following:

<IfModule LiteSpeed>
CacheLookup on

2. Move the LiteSpeedCache directory to /extensions in the MediaWiki directory

3. Edit LocalSettings.php in the MediaWiki root directory, and add the following near the end:

wfLoadExtension( 'LiteSpeedCache' );

4. After you login to media wiki special page, under Data and Tools,there is LiteSpeed cache setting like the following:

You should also turn public cache and private cache on there. The default settings are “off”.


From the MediaWiki administrator panel navigate to Special pages > LiteSpeed Cache, and edit the page to enable public cache:

Set LiteSpeed Public Cache Enabled to checked and save the page.

Verify Cache Setup

If a resource is served from LSWS cache, the server response header contains X-LiteSpeed-Cache: Hit.

Load the URL and check the headers through Network tab of the developer tool. You should see something like this:

GET /wiki/index.php/Main_Page HTTP/1.1
Accept	text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding	gzip, deflate, br
Accept-Language	en-US,en;q=0.5
cache-control	public, max-age=2592000
server	LiteSpeed
vary	Accept-Encoding, Cookie
x-litespeed-cache	hit
