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.

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!
