The **Browser Cache Rule** feature for Dynamic Content Acceleration operates the same way as in Static Content Delivery.\ It controls browser-side caching by defining cache duration, cache modes, and rule priorities for different URL patterns, directories, or file types. These rules determine how browsers store and revalidate dynamic content, independent of CDN edge caching behavior. For configuration details, rule types, and examples, refer to the main documentation:\ **Learn more in the** [**Browser Cache Rule documentation**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/browser-cache-rule.md)**.** --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://clients.medianova.com/products/performance-cdn/dynamic-content-acceleration/advanced-configuration/caching/browser-cache-rule.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
