# Shared Cache The **Shared Cache** feature for Dynamic Content Acceleration operates the same way as in Static Content Delivery.\ It determines whether CDN edge nodes use an isolated cache namespace for your account (**Default**) or a shared cache namespace across multiple accounts that use the same Domain Cache Key (**Share**). When shared mode is enabled, identical content is cached once and reused across participating accounts, improving efficiency and reducing redundant origin requests. For configuration details, cache modes, and examples, refer to the main documentation:\ **Learn more in the** [**Shared Cache documentation**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/shared-cache.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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://clients.medianova.com/products/performance-cdn/dynamic-content-acceleration/advanced-configuration/caching/shared-cache.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
