# Caching

Configure how content is cached, refreshed, and served by Medianova CDN.

Caching settings control how CDN Resources store and reuse responses at the edge. These settings can be used to define cache lifetimes, control cache behavior for query strings and specific response types, and determine how cached content is handled under different request and origin conditions.

Caching configuration is managed per CDN Resource in the [Medianova Control Panel](https://cloud.medianova.com).

### Cache Configuration

The **Caching** section includes settings for controlling different aspects of CDN cache behavior, including:

* [**Edge Cache Expiration**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/edge-cache-expiration.md) – Control how long content remains cached at the CDN edge.
* [**Browser Cache Rule**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/browser-cache-rule.md) – Control browser-side caching behavior.
* [**Query String Caching**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/query-string-caching.md) – Define how query strings affect cache behavior.
* [**ETag Verification**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/etag-verification.md) – Configure validation behavior for cached content using ETag headers.
* [**Error Status Code Cache Expiration**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/error-status-code-cache-expiration.md) – Configure caching behavior for supported error responses.
* [**Shared Cache**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/shared-cache.md) – Configure shared cache behavior for the CDN Resource.
* [**Stale Cache**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/stale-cache.md) – Control whether stale cached content can be used under supported conditions.
* [**Robots.txt File**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/robots.txt-file.md) – Configure caching behavior for `robots.txt`.
* [**Range Based Caching**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/range-based-caching.md) – Configure caching behavior for range-based requests.
* [**Mobile Device Cache**](/products/performance-cdn/static-content-delivery/advanced-configuration/caching/mobile-device-cache.md) – Control cache behavior for mobile device requests.

Select the relevant caching feature in the documentation for its configuration options and behavior.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://clients.medianova.com/products/performance-cdn/static-content-delivery/advanced-configuration/caching.md?ask=<question>&goal=<user_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.
