Purging the page cache
The default behavior of the VIP Platform page cache is configured to maximize cache hit rates and improve performance for all WordPress and Node.js applications. The default cache clearing behaviors of the page cache are also configured for application resilience while ensuring that updated content is served in a timely manner.
If needed, additional methods are available for purging the page cache for specific URLs or assets at a specific time or based on specific criteria.
Note
When purging a URL from the page cache, all variants of the URL’s GET parameters will also be purged. Purging a post with slug hello-world will also purge other cached variants such as /hello-world/?a=1&b=1 as well as /hello-world/?b=1&a=1. It is not possible to purge a specific variant of a URL without purging all if its other variants.

Automatic cache purging for WordPress content
By default, updating or publishing a WordPress page or a post of any kind (built-in post or custom post type) will cause some caches in the page cache to automatically clear.
-
Purge programmatically
Select behaviors of the VIP page cache can be controlled using VIP’s Cache API. Some of the Cache API controls are provided by VIP MU plugins and must be implemented by a WordPress application.
-
Purge by URL
Content cached by the page cache can be purged on demand in the VIP Dashboard, with VIP-CLI, or in a site’s WordPress Admin tool bar.
