Web Cache Web Server Configuration - cPanel/WHM Single Site

Create a file named “lscache.conf” with the following content in directory /usr/local/apache/conf/includes/:

<IfModule Litespeed>
CacheRoot /home/lscache/
</IfModule>

Note: It is recommended to set the server level cache root to /home/lscache/ or a disk partition with enough space. Server level cache root will only be used when vhosts cache root not set.

Then

cat /usr/local/apache/conf/includes/lscache.conf >> /usr/local/apache/conf/includes/pre_main_global.conf

After applying your cache storage settings, perform a graceful restart of LiteSpeed web server to have these changes take effect.

service lsws restart

Add the following Apache style configuration directive in .htaccess to enable cache lookup.

<IfModule LiteSpeed>
   CacheLookup public on
</IfModule>
