# Route to a different origin based on origin response

If response to the original request is not `200 OK` or a redirect, send to another origin.

JavaScript

```

export default {

  async fetch(request) {

    // Send original request to the origin

    const response = await fetch(request);


    // If response is not 200 OK or a redirect, send to another origin

    if (!response.ok && !response.redirected) {

      // First, clone the original request to construct a new request

      const newRequest = new Request(request);

      // Add a header to identify a re-routed request at the new origin

      newRequest.headers.set("X-Rerouted", "1");

      // Clone the original URL

      const url = new URL(request.url);

      // Send request to a different origin / hostname

      url.hostname = "example.com";

      // Serve response to the new request from the origin

      return await fetch(url, newRequest);

    }


    // If response is 200 OK or a redirect, serve it

    return response;

  },

};
