LSCache Plugin for XenForo 2

lscache-xf2

LSCache Plugin for XenForo 2

Feature list:

• Powerful defense against DDOS attacks.
• Significantly reduce server load (and MySQL queries).
• Guests pages are cached by LiteSpeed cache.

Installation:

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

Configuration:

• Add the following .htaccess rules, replacing 'xf_user' by the custom cookie prefix used if changed in XenForo's configuration, and '360' by the number of seconds the content should remain cached (Recommended < 10 mins):

    # LiteSpeed XenForo cache
    <IfModule litespeed>
        CacheLookup public on
        RewriteEngine On
         # cache
         RewriteCond %{HTTP_COOKIE} !(xf_lscxf_logged_in|xf_user|xf_session_admin) [NC]
         RewriteCond %{REQUEST_URI} !/install/ [NC]
         RewriteRule .* - [E=Cache-Control:max-age=360,E="cache-vary:xf_style_id,xf_language_id"]
         # no cache
         RewriteCond %{HTTP_COOKIE} (xf_lscxf_logged_in|xf_user|xf_session_admin) [NC]
         RewriteRule .* - [E=Cache-Control:vary=loggedin,E=Cache-Control:no-cache]
    </IfModule>
