-**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.
+**Note:**
+  * **"Enable Public Cache"** should always be "Not Set" or "No" unless you want to enable cache globally, which is definitely not recommended.
+  * **Check Public Cache** better set to "Not Set" but should never be "No" otherwise it will turn off the cache lookup and LScache won't work.
+===== Restart LSWS =====
+Please perform a graceful restart of LiteSpeed Web Server after any configuration change to the server.
