# Edge and Browser Cache TTL

## Edge Cache TTL

Edge Cache TTL (Time to Live) specifies the maximum time to cache a resource in the Cloudflare global network. Edge Cache TTL is not visible in response headers and the minimum Edge Cache TTL depends on plan type.

|                        | Free    | Pro    | Business | Enterprise |
| ---------------------- | ------- | ------ | -------- | ---------- |
| Availability           | Yes     | Yes    | Yes      | Yes        |
| Minimum Edge Cache TTL | 2 hours | 1 hour | 1 second | 1 second   |

For more information on how to set up Edge Cache TTL, refer to [Cache rules](https://developers.cloudflare.com/cache/how-to/cache-rules/settings/#edge-ttl).

## Browser Cache TTL

The Browser Cache TTL sets the expiration for resources cached in a visitor’s browser. By default, Cloudflare honors the cache expiration set in your `Expires` and `Cache-Control` headers but overrides those headers if:

* The value of the `Expires` or `Cache-Control` header from the origin web server is less than the Browser Cache TTL Cloudflare setting.
* The origin web server does not send a `Cache-Control` or an `Expires` header.

Unless specifically set in a cache rule, Cloudflare does not override or insert `Cache-Control` headers if you set **Browser Cache TTL** to **Respect Existing Headers**.

Note

* Setting high Browser Cache TTL values means that the assets will be cached for a long time by users’ browsers.
* If you modify cached assets, the new assets may not be displayed to repeat visitors before the Browser Cache TTL expires.
* Purging Cloudflare’s cache does not affect assets stored by a visitor’s browser.
