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/cache-rules/examples/edge-ttl/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

[Create a cache rule](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cache/how-to/cache-rules/create-dashboard/) to adjust edge cache TTL for caching resources on Cloudflare edge 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
  * **Setting**: Edge TTL  
    * Ignore cache-control header and use this TTL  
      * **Input time-to-live (TTL)**: _1 day_
