Web Cache Web Server Configuration - Apache Config (No Control Panel) Multi-Site

Set a server level cache root by add the following to your server level Apache config file:

<IfModule Litespeed>
CacheRoot /tmp/lscache
</IfModule>

Note: make sure /tmp/lscache exists and server readable/writeable (nobody:nobody for cPanel). CacheRoot is an absolute path for server level setting

The vhost host level cache root is normally a per user cache root set to a subfolder under a user's home directory.

If using a virtual host include file (as opposed to .htaccess) a relative path can be used for “CacheRoot” such as

<IfModule LiteSpeed>
  CacheRoot lscache
</IfModule>

The cache directory will be created automatically as “lscache” if not exists under user's home directory.

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

<IfModule LiteSpeed>
   CacheLookup public on
</IfModule>

Perform a web server graceful restart.

Note: Shared hosting providers can selectively enable LSCache by setting Check Public Cache to “No” at the server level (Configuration»Server»Cache»Cache Policy) and then adding this directive in the .htaccess file of a specific WordPress installation. This will have the effect of turning on LSCache for only this site, allowing you to choose which sites have caching enabled.
