How to enable the LiteSpeed Crawler

Introduction

The LiteSpeed Crawler is a cache plugin that will regularly keep the cache for your websites updated to make sure that visitors don't encounter any uncached pages.

Per LiteSpeed's documentation, they do recommend that the crawler only be enabled if your server has enough resources.

Procedure

The LiteSpeed Crawler can be enabled server-wide or per vhosts to reduce resource usage.

The following code block will need to be added to enable the crawler:

<IfModule Litespeed>
 CacheEngine on crawler
</IfModule>

Server-Wide:

/etc/apache2/conf.d/includes/pre_main_global.conf

Per Vhost:

HTTP vhost: 

/etc/apache2/conf.d/userdata/std/2_4/<user>/<domain>/

HTTPS vhosts:

/etc/apache2/conf.d/userdata/ssl/2_4/<user>/<domain>/
