XF2 ADD-ON LiteSpeed Cache for XF2 - Community 2.2.3-1

Compatible XF Versions2.1 , 2.2Visible BrandingNo
Developed by LiteSpeed Technologies - the LiteSpeed Cache Plugin for XenForo 2 (LSCXF2) is a PHP-based plugin that communicates with your installation of LiteSpeed Web Server(LSWS) and its built-in page cache, LSCache. Because LSCache is built directly into LSWS, overhead is significantly reduced and caching can be done more efficiently than with other PHP-based caches.

The current community version of LSCXF2 will only cache and serve pages for non-logged in users. After a user has logged in, their page requests will always hit the backend.

Additional Plugin Features

• Significantly reduce server load and improve site performance through automatic page caching.
• Support for HTTPS, HTTP/2, & QUIC out-of-box

Installation

1. Download the LiteSpeed Cache for XenForo plugin package.
2. Disable any other page caches as these will interfere with LSCXF2.
3. Access the server hosting your XenForo installation, either directly or using ssh/sftp.
4. From the unzipped LSCXF2 folder, copy all files under upload to the upload folder of your XenForo installation.
5. In the XenForo control panel, navigate to the Add-ons section to complete the installation.

Configuration
Once you have downloaded and installed the plugin package, edit .htaccess with the code shown below, making the following changes where appropriate:

• Replace xf_user with the new value, if you changed it in XenForo Configuration.
• If you want to cache for more or less than 360 seconds, change 360 to the number of seconds you wish. (Recommended < 10 minutes):

Code:
# LiteSpeed XenForo cache
<IfModule litespeed>
CacheLookup public on
RewriteEngine On
# cache
RewriteCond %{HTTP_COOKIE} !xf_user [NC]
RewriteRule .* - [E=Cache-Control:max-age=360]
# no cache
RewriteCond %{HTTP_COOKIE} xf_user [NC]
RewriteRule .* - [E=Cache-Control:vary=loggedin]
RewriteCond %{HTTP_COOKIE} xf_user [NC]
RewriteRule .* - [E=Cache-Control:no-cache]
</IfModule>
