# Route by country

> Send visitors from specific countries to a different origin using the CDN-RequestCountryCode header.

bunny.net adds the [`CDN-RequestCountryCode`](/cdn/vary-cache) header to every request. This script reads it and routes the listed countries to a second origin.

```typescript theme={null}
import * as BunnySDK from "@bunny.net/edgescript-sdk";

const PRIMARY = "https://primary.example.com";
const ALTERNATE = "https://alternate.example.com";

// Countries routed to the alternate origin
const ALTERNATE_COUNTRIES = new Set(["NZ", "FI"]);

BunnySDK.net.http.serve(async (request: Request): Promise<Response> => {
  const country = request.headers.get("CDN-RequestCountryCode") ?? "";
  const variant = ALTERNATE_COUNTRIES.has(country) ? ALTERNATE : PRIMARY;

  const target = new URL(request.url);
  const origin = new URL(variant);
  target.protocol = origin.protocol;
  target.host = origin.host;

  return fetch(new Request(target, request));
});
```

Add or remove entries in `ALTERNATE_COUNTRIES` to change which countries get the alternate origin.
