LiteSpeed Cache for Joomla Recache Settings

Usually, when a page is purged from the cache, it remains uncached until a visitor comes along and requests the page. These settings change that behavior.

With Auto Recache enabled, LiteSpeed will automatically re-cache purged pages, which means that your site’s visitors will have a lower chance of ever encountering uncached content. It's a good thing to keep your cache warm in this manner, however it has the potential to impact server performance.

If you have plenty of resources, and server performance isn't at risk, choose Aggressive. The aggressive option is very thorough about recaching all of the pages that are related to a particular purge. If you prefer to use fewer resources, select Moderate, which recaches most of the related pages, but may miss some of them.

Note: Auto Recache doesn't kick in after an automatic Purge All command. If you wish to re-populate the cache in that event, you will need to do so manually from the LiteSpeed Cache Settings (ESI Module Settings) screen, located in the Components menu.

Another way to control server impact is by setting a maximum recaching duration. For example, you can specify that the server should spend at most 10 seconds recaching content. After that, it should stop, even if all of the recaching is not complete. The default value here is 5 seconds, but you can adjust that based on what your server can handle.

This option allows you to recache URLs that are generated by a component but are not part of the menu system.
