+====== LSCache + Drupal Configuration ======
-LSCache, similar to Varnish cache, is a simpler and more efficient page caching solution built-in to LiteSpeed Web Server. When used in conjunction with Drupal 7, you can expect significant performance gains with a quick and easy setup. Cache management is also made significantly easier and more flexible with the ability to use rewrite rules to customize cache behavior.

+Below are some recommended configurations to enable LSCache and get it working with your Drupal site(s).
+===== Configure Server/Virtual Host Level Cache Root And Cache Policy =====
-===== Server Level Settings =====
+Server/VirtualHost level cache storage needs to be configured properly for your environment. Select your server setup from the **Web Server Configuration** section of our **[[litespeed_wiki:cache:common_installation#web_server_configuration|LiteSpeed Cache Installation Guide]]** and follow the instructions to set the server/virtual host level cache root and cache policy.
-From the LSWS WebAdmin Console navigate to **Server >> Cache**.
-Under **Cache Storage Settings**, set **Storage path** to the directory you want to use to store cached objects.
+===== Rewrite rules =====
-For example:
-    Storage Path: /tmp/diskcache
-It is recommended that this directory be on a dedicated disk or disk array in RAID 0 configuration.
-Under **Cache Policy**, we recommend using the following settings:
-    Enable Cache:No
-    Cache Request with Query String:Yes
-    Cache Request with Cookie:Yes
-    Cache Response with Cookie:Yes
-    Ignore Request Cache-Control:Yes
-    Ignore Response Cache-Control:Yes
-    Enable Private Cache: No
-**Note:** **Enable Cache** has been set to “No” globally as caching will instead be enabled through the use of rewrite rules to control what pages will be cached and for how long.
-===== Website Level Settings =====
 At the top of your .htaccess file, located in the document root of your website, add the following:

-Where "your_domain_name.com" is the web address of your Drupal 7 site.
-We recommend using a different domain for your backend so that you can add/edit/preview a website's content through the admin domain without worrying about these changes being cached and seen by visitors.
+**Note1:**  The **"CacheDisable public /"** directive is used to help protect against globally enabled caching and is optional. Instead, the server's global cache settings should be checked to ensure that cache is not enabled globally. **Do NOT** use **"CacheEnable public /"** here as it will enable caching for all URLs belonging to this virtual host, including admin pages.

-__**Adding a cron job to delete outdated cache files**__
-While optional, it is a good idea to clear out old cache files that are past the set **Time To Live (TTL)**. To do this enter the following in /etc/crontab
+Please verify to see if you can see "X-LiteSpeed-Cache: hit" by following [[litespeed_wiki:cache:no-plugin-setup-guidline#verify_that_pages_are_served_from_the_cache|this wiki]].
-  /10 * * * * root find /tmp/diskcache -type f -mmin +8 -delete 2>/dev/null
+===== Deleting Outdated Cache Files Using A Cron Job =====
-**Note:** This cron job deletes cached files that are more than 8 minutes old every 10 minutes. Since the cache TTL is set at 120 seconds (2 minutes), it is safe to delete these files that are way passed TTL.
