 ====== LiteSpeed Cache for Drupal 8 ======
+**NOTE: This plugin is only for Drupal 8. If you are running an earlier version of Drupal, you will need to use [[litespeed_wiki:cache:no-plugin-drupal|LSCache via rewrite rules]].**
 Drupal 8 is significantly changed from Drupal 7. The developers switched from procedural programming to object-oriented programming. Drupal 8 has a built-in page cache (for static content) and a dynamic page cache for logged in users. The latter basically works as a reverse proxy written in PHP. The built-in proxy is good if you have no other options, however, with the LiteSpeed Cache plugin you will see a great improvement in performance for your Drupal 8 site.

+===== Verify LiteSpeed Cache is Working  =====
+Look for the response header ''X-LiteSpeed-Cache: hit'' in the browser developer tools to verify a page is being served from LiteSpeed Cache. Here's how:
+  - Open the Chrome/Firefox developer tools on a non-logged-in browser and navigate to your site. Open the **Network** tab.
+  - Refresh the page.
+  - Click the first resource (this should be an HTML file). The resource's headers should appear, and ''X-LiteSpeed-Cache: hit'' should be among them.
+  - If you see ''X-LiteSpeed-Cache: miss'' instead, refresh the page and check the header again.
+  - If you continue to not see ''X-LiteSpeed-Cache: hit'', it means LiteSpeed is not working or is not enabled properly. Please go back to the beginning and make sure you have carried out each step properly.
