Before installing and activating the LSCache plugin, deactivate all other full-page cache plugins.
You can still use other types of cache (like object cache or browser cache), but only one full-page cache should be used at a time.
To avoid a potential conflict with LiteSpeed Web Server, you may want to keep Joomla!'s gzip function Off. You'll find this setting in System > Global Configuration > Server > Gzip Page Compression.
Server Configuration
Modify the .htaccess file in the Joomla! site directory, and add the following directives:
<IfModule LiteSpeed>
CacheLookup on
</IfModule>
If your Joomla! site has a separate mobile view, please also add the following:
<IfModule LiteSpeed>
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} Mobile|Android|Silk/|Kindle|BlackBerry|Opera\ Mini|Opera\ Mobi [NC]
RewriteRule .* - [E=Cache-Control:vary=ismobile]
RewriteCond %{REQUEST_URI} enquiry [NC]
RewriteRule .* - [E=Cache-Control:no-cache]
</IfModule>
Extension Installation
- Download the LSCache for Joomla! package.
- From the Joomla! Administration menu, navigate to Extensions > Manage > Install.
- Select the Upload Package File tab, and drag the zip file into the window, or press the button to browse for the file.
- The plugin will be automatically installed and enabled.
Verify the Plugin is Enabled
Navigate to Extensions > Plugins. If you have a lot of plugins listed, type LiteSpeed into the search box to bring up the LiteSpeed Cache Plugin.
Look for the green check mark next to the plugin name. This indicates that the plugin is installed and enabled. If you see a red X instead, click the red X to enable the plugin. Once you’ve done that, the green check mark should appear, and you are good to go.
If you wish to disable the plugin in the future, you may click the green check mark to toggle it back to the red X.
Verify Your Site is Being Cached
There's a simple way to see if a URL is cached by LiteSpeed: the LSCache Check Tool.
Enter the URL you wish to check, and the tool will respond with an easy-to-read Yes or No result, and a display of the URL's response headers, in case you want to examine the results more closely.
