# http.host

`http.host` String

The hostname used in the full request URI.

The `http.host` field contains the `Host` header from the original request.

If you have configured [Origin Rules](https://developers.cloudflare.com/rules/origin-rules/) that change the hostname, they will not be reflected in the `http.host` field value.

Example value:

```txt
"www.example.org"
```
