Web Cache Web Server Configuration - LiteSpeed Native

Note: If you are running your server with cPanel/WHM or Plesk, you should not follow the instructions on this page.

From the WebAdmin Console, navigate to Configuration » Server » Cache and set Storage Path under “Cache Storage Settings”.

For example:
Storage Path: /home/lscache/.

From the WebAdmin Console, navigate to Configuration » Virtual Hosts » <vh_name> » Cache and set Storage Path under “Cache Storage Settings”.

For example:
Storage Path: /home/<vh_user>/lscache/.

If it does not exist, the cache directory will be created automatically by LiteSpeed Web Server during startup as lscache under the user's home directory.

Notes: If different vhosts share the same document root, these vhosts have to share the same vhost level cache root directory.

Under Cache Policy at either the Server or Virtual Host level, leave all cache policies as “not set”.

The following screenshot shows the cache policy settings at the virtual host level:

Add the following Apache style configuration directive to .htaccess file of a specific WordPress installation to enable cache lookup.

<IfModule LiteSpeed>
  CacheLookup public on
</IfModule>

This will have the effect of turning on LSCache for only this site, allowing you to choose which sites have caching enabled.

NOTE: The Publicly Cache All and Private Cache All settings are not available at the server level, as it is strongly recommended that you not enable caching server-wide. If you have a need for global caching, you may configure a Context for that purpose.

This can be configured in both the server level and the vhost level but is more commonly done at the server level.

In your LiteSpeed Web Server Web Admin, navigate to Configuration > Server > General and scroll to about halfway down the page. You should see an HT Access section.

You should select the checkboxes to match the screenshot above.

Note: if you're enabling this at the vhost level, the same settings should be listed in the LiteSpeed Web Server Web Admin under the Configuration > Virtual Hosts > <Your VHost> > General and the same checkboxes should be checked.

Please perform a graceful restart of LiteSpeed Web Server after any configuration change to the server.
