## Cache Response Rules

Mar 24, 2026 

[ Cache / CDN ](https://developers.cloudflare.com/cache/) 

You can now control how Cloudflare handles origin responses without changing your origin. Cache Response Rules let you modify `Cache-Control` directives, manage cache tags, and strip headers like `Set-Cookie` from origin responses _before_ they reach Cloudflare's cache. Whether traffic is cached or passed through dynamically, these rules give you control over origin response behavior that was previously out of reach.

#### What changed

Cache Rules previously only operated on request attributes. Cache Response Rules introduce a new response phase that evaluates origin responses and lets you act on them before caching. You can now:

* **Modify `Cache-Control` directives**: Set or remove individual directives like `no-store`, `no-cache`, `max-age`, `s-maxage`, `stale-while-revalidate`, `immutable`, and more. For example, remove a `no-cache` directive your origin sends so Cloudflare can cache the asset, or set an `s-maxage` to control how long Cloudflare stores it.
* **Set a different browser `Cache-Control`**: Send a different `Cache-Control` header downstream to browsers and other clients than what Cloudflare uses internally, giving you independent control over edge and browser caching strategies.
* **Manage cache tags**: Add, set, or remove cache tags on responses, including converting tags from another CDN's header format into Cloudflare's `Cache-Tag` header. This is especially useful if you are migrating from a CDN that uses a different tag header or delimiter.
* **Strip headers that block caching**: Remove `Set-Cookie`, `ETag`, or `Last-Modified` headers from origin responses before caching, so responses that would otherwise be treated as uncacheable can be stored and served from cache.

#### Benefits

* **No origin changes required**: Fix caching behavior entirely from Cloudflare, even when your origin configuration is locked down or managed by a different team.
* **Simpler CDN migration**: Match caching behavior from other CDN providers without rewriting your origin. Translate cache tag formats and override directives that do not align with Cloudflare's defaults.
* **Native support, fewer workarounds**: Functionality that previously required workarounds is now built into Cache Rules with full Tiered Cache compatibility.
* **Fine-grained control**: Use expressions to match on request and response attributes, then apply precise cache settings per rule. Rules are stackable and composable with existing Cache Rules.

#### Get started

Configure Cache Response Rules in the [Cloudflare dashboard ↗](https://dash.cloudflare.com/?to=/:account/:zone/caching/cache-rules) under **Caching** \> **Cache Rules**, or via the [Rulesets API ↗](https://developers.cloudflare.com/ruleset-engine/rulesets-api/). For more details, refer to the [Cache Rules documentation ↗](https://developers.cloudflare.com/cache/how-to/cache-response-rules/).
