WordPress Plugin: Keep Your Cache Up-to-Date

Here’s a plugin that will automatically repopulate your LiteSpeed Cache when an article gets updated on WordPress — enjoy LSCache speed and article updates without waiting for cache to expire.

To install the plugin, just download lscache-purge plugin and add to WP plugins (Plugins => Add New => Upload).

Or, install directly using the Search tab and the plugin URL (http://www.litespeedtech.com/packages/wp-plugins/lscache-purge.zip).

Once installed, go to Installed Plugins and activate it.

The plugin comes with GUI under Settings for choosing the purge cache method — purge or refresh.

For details on refreshing the cache, refer to this blog entry.

Next, enable LiteSpeed Cache, if you have not done so.

WebAdmin console => Configuration => Server => Cache

For more details on how to set up LiteSpeed Cache, refer to our wiki.

Note the “Do-Not-Cache URL” box. It specifies URL patterns not to be cached. In this case, URLs that start with “/wp-admin” are excluded from being cached.

That’s it. LSCache will take care of the rest. Have fun!
