# Purge The **Purge** feature for **Dynamic Content Acceleration** works the same way as for **Static Content Delivery**.\ It allows you to **instantly invalidate cached content** across all Medianova CDN cache layers, ensuring that users always receive the most recent version of your dynamic assets. Purge operations remove outdated or modified files from CDN cache and trigger fresh retrieval from your origin upon the next request.\ This guarantees consistency and fast propagation across all edge and shield locations. For detailed usage steps, behavior, and best practices, please visit the main Purge documentation below: **Learn all about** [**Purge**](/products/performance-cdn/static-content-delivery/advanced-configuration/purge.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
