-====== How to disable cache globally but enable for a particular virtual host on shared hosting environment? ======
+====== Enabling Cache/ESI/Crawler for an Individual Virtual Host ======
+A shared hosting provider may want to maintain server-wide control over the enabling and disabling of cache-related services. These services include caching itself as well as the ESI and Crawler functions available with our WordPress LSCache Plugin. By disabling the cache globally and enabling it for a particular virtual host, shared hosting providers may offer LSCache as an add-on service to their customers.
+''esi'' and ''crawler'' are disabled by default during the initial installation and you will need to enable them specifically.
 ===== CacheEngine on/off directives =====
-Shared hosting provider may want to have more control on cache on/off, esi on/off, crawler on/off (esi and crawler are only applied to WordPress cache plugin at the time of this writing). This way, shared hosting provider provide lscache as an add on services to their customer. You can use the following directives to disable cache on a global level, such as cpanel's pre_main_global, and enable it on virtual host include file ( but not .htaccess) to enable it individually.
+Use the following directives to disable cache on a global level, such as with cPanel's ''pre_main_global'', and enable it individually in a virtual host include file ( but not ''.htaccess'').
 To disable cache:
+  <IfModule Litespeed>
   CacheEngine off
+  </IfModule>
 To enable cache, esi and crawler:
+  <IfModule Litespeed>
   CacheEngine on esi crawler
+  </IfModule>
 To enable cache, but neither esi nor crawler:
+  <IfModule Litespeed>
   CacheEngine on
+  </IfModule>
-===== Examples: How to disable cache globally and enabling it individually on a cpanel server? =====
+===== Examples: cPanel =====
-The directives should be placed within <IfModule Litespeed> .. </IfModule>, could be right after the CacheRoot configurations.
+To disable cache globally, add the directive to the ''/usr/local/apache/conf/includes/pre_main_global.conf'' file for EA3 or the ''/etc/apache2/conf.d/includes/pre_main_global.conf'' file for EA4. It should be placed within ''<IfModule Litespeed> .. </IfModule>'', right after the CacheRoot configuration, like so:
-For example for cPanel server, to disable cache globally:
- Add the above to the /usr/local/apache/conf/includes/pre_main_global.conf file for EA3 or the /etc/apache2/conf.d/includes/pre_main_global.conf file for EA4
   <IfModule Litespeed>

 ===== Other control panels =====
-If you use other control panels, you should be able to use the similar directives to control the cache for your shared hosting accounts.

 ===== Enabling the WordPress Crawler =====
-Enabling crawler is applicable for LiteSpeed WordPress plugin at the time of this writing and may be expanded to other application support when these LiteSpeed cache plugins become available.
