Installation¶

Before installing and activating the LSCache plugin, deactivate all other full-page cache plugins.

Extension Installation¶

1. Download LSCMW like so:

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

2. Unzip the downloaded file:

   unzip master.zip
   

3. Find the .htaccess file in the MediaWiki root directory, or create one if it doesn't exist. Add the following to the file to enable LSCache at the server level:

   <IfModule LiteSpeed>
   CacheLookup on
   </IfModule>
   

4. Move the LiteSpeedCache directory to /extensions in the MediaWiki directory
5. Edit LocalSettings.php in the MediaWiki root directory, and add the following near the end:

   wfLoadExtension( 'LiteSpeedCache' );
   

6. Log into MediaWiki and from the administrator panel, navigate to Special pages > Data and Tools > LiteSpeed Cache.
   
   
7. Set LiteSpeed Public Cache Enabled to checked and click the Save Cache Setting button.

Verify Your Site is Being Cached¶

You can verify a page is being served from LSCache through the following steps:

1. From a non-logged-in browser, navigate to your site, and open the developer tools (usually, right-click > Inspect). Open the Network tab.
2. Refresh the page.
3. Click the first resource. This should be an HTML file. For example, if your page is http://example.com/webapp/, your first resource should either be something like example.com/webapp/ or webapp/.
4. You should see headings similar to these:

   X-LiteSpeed-Cache: miss
   X-LiteSpeed-Cache-Control:public,max-age=1800
   X-LiteSpeed-Tag:B1_F,B1_ 
   

   These headings mean the page had not yet been cached, but that LiteSpeed has now stored it, and it will be served from cache with the next request.
5. Reload the page and you should see X-LiteSpeed-Cache: hit in the response header. This means the page is being served by LSCache and is configured correctly.
