# Set response header with a static value

Create a response header transform rule (part of Transform Rules) to set an `X-Bot-Score` HTTP header in the response to a static value (`Cloudflare`).

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://mchen-ai-models-sync.previews.developers.cloudflare.com/rules/transform/examples/set-response-header-static-value/index.md)|[Agent setup](https://mchen-ai-models-sync.previews.developers.cloudflare.com/agent-setup/)

The following response header transform rule sets a header named `X-Source` to a static value (`Cloudflare`) in the HTTP response:

Text in **Expression Editor**:

```txt
starts_with(http.request.uri.path, "/en/")
```

Selected operation under **Modify response header**: _Set static_

**Header name**: `X-Source`

**Value**: `Cloudflare`

This rule would overwrite any existing `X-Source` headers already present in the HTTP response.
