# Browser Cache TTL

Browser Cache TTL

Note

If you are migrating from Page Rules and you want to keep Page Rules behavior, you need to create two specific rules before creating this rule. For more details refer to [Migration from Page Rules](https://developers.cloudflare.com/cache/how-to/cache-rules/page-rules-migration/).

[Create a cache rule](https://developers.cloudflare.com/cache/how-to/cache-rules/create-dashboard/) to adjust browser cache TTL for caching resources in the browser to one day for any hostname containing `example.com`:

* **When incoming requests match**: Custom filter expression  
   * Using the Expression Builder:  
   `Hostname contains "example.com"`  
   * Using the Expression Editor:  
   `(http.host contains "example.com")`
* **Then**:  
   * **Cache eligibility**: Eligible for cache  
   * **Browser TTL**: Override origin and use this TTL  
   * **Input time-to-live (TTL)**: _1 day_
