# Set Browser Cache TTL

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cache/how-to/edge-browser-cache-ttl/set-browser-ttl/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

Specify a time for a visitor’s Browser Cache TTL to accelerate the page load for repeat visitors to your website. To configure cache duration within Cloudflare’s data centers, refer to [Edge Cache TTL](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cache/how-to/cache-rules/settings/#edge-ttl).

By default, Cloudflare honors the cache expiration set in your `Expires` and `Cache-Control` headers. Cloudflare overrides any `Cache-Control` or `Expires` headers with values set via the **Browser Cache TTL** option under **Caching** on your dashboard if:

* The value of the `Cache-Control` header from the origin web server is less than the **Browser Cache TTL** setting. This means that **Browser cache TTL** value needs to be higher than origin `max-age`.
* The origin web server does not send a `Cache-Control` or an `Expires` header.

Unless specifically set in a [Cache Rule](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cache/how-to/cache-rules/), Cloudflare does not override or insert `Cache-Control` headers if you set **Browser Cache TTL** to **Respect Existing Headers**.

Nevertheless, the value you set via Cache Rule will be ignored if `Cache-Control: max-age` is higher. In other words, you can override to make browsers cache longer than Cloudflare's edge but not less.

## Set Browser Cache TTL

Note

If you modify cached assets, the new asset is not displayed to repeat visitors before the Browser Cache TTL duration. [Purging Cloudflare’s cache](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cache/how-to/purge-cache/) does not affect assets cached in a visitor’s browser.

1. In the Cloudflare dashboard, go to the **Caching** page.  
[Go to **Configuration** ↗](https://dash.cloudflare.com/?to=/:account/:zone/caching/configuration)
2. Under **Browser Cache TTL**, select the desired cache expiration time from the drop-down menu.

The **Respect Existing Headers** option tells Cloudflare to honor the settings in the `Cache-Control` headers from your origin web server.
