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.

wget <nowiki>https://github.com/litespeedtech/lscache_mediawiki/archive/master.zip</nowiki>

Unzip the downloaded file with:

unzip master.zip

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

   <IfModule LiteSpeed>
   CacheLookup on
   </IfModule>

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. Log in to MediaWiki and from the administrator panel, navigate to 'Special pages > Data and Tools > LiteSpeed Cache'.

Edit the page to enable public cache:

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

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

Load the URL https://yourdomain.com/wiki/index.php/Main_Page and check the headers through the Network tab of the brower's developer tool. You should see something like this:
