# Page Caching Configuration

For our server side page caching to work properly, the **Nginx Helper** plugin must remain installed and configured properly. If you delete the Nginx Helper plugin, the server will have difficulty clearing the cache on content updates. You can always download and re-install the [Nginx Helper plugin from the WordPress Org Repository](https://wordpress.org/plugins/nginx-helper/) at any time.

## Settings

When your website is first setup on our servers, we configure the default settings for you (Purging Options, Caching Method, Redis Settings) so there should be no reason to change these settings on the settings page for the plugin.

For your reference, **Enable Purge** should be checked in **Purging Options**, **Redis cache**should be selected as the**Caching Method. **Under**Redis Settings, ****Hostname** should be set to **127.0.0.1** with a** Port **of** 6379**, and **Prefix** is set to**nginx-cache:**(the trailing colon is critical).

Under** Purging Conditions** you can modify what content updates you would like to trigger the purging and updating of cache. Note the Custom Page URL section at the bottom where you can specify specific urls you'd like to clear when content is updated.
