Configuration

This step is optional. Once the plugin is activated, your cache is already up and running, but on the configuration screen, you can customize few settings.

Go to

http://example.com/admin/config/development/lscache

• Warmup this site: Warm up the LSCache of the current Drupal site. It will also warm up Private Cache for Logged In Users if enabled.
• Clear this site: Clears the LSCache of the current Drupal site. It will not clear the LSCache of other sites if you have multiple CMS sites running on the same virtual host.
• Public Cache TTL: Amount of time LiteSpeed Web Server will save pages in the public cache.
• Private Cache TTL: Amount of time LiteSpeed web server will save ESI Block Contents in the Private cache. OpenLiteSpeed does not support Private Cache.
• ESI Blocks Setting: The list of ESI blocks on general logged in pages. The ESI Block name should be the same as the div id inside the HTML source. For example, in the following div block, the ESI Block name would be bar-administrator:

   <div id="bar-administrator">...<div>
  

• Debug: If turned on, LiteSpeed Cache will print the LSCache header to LSWS log files.
