Country code redirect
Redirect a response based on the country code in the header of a visitor.
export default {  async fetch(request) {    /**     * A map of the URLs to redirect to     * @param {Object} countryMap     */    const countryMap = {      // Replace the country codes and target URLs with ones that apply to your case.      US: "https://example.com/us",      EU: "https://example.com/eu",    };
    // Use the cf object to obtain the country of the request    // more on the cf object: https://developers.cloudflare.com/workers/runtime-apis/request#incomingrequestcfproperties    const country = request.cf.country;
    // If country is not null and is defined in the country map above, redirect.    if (country != null && country in countryMap) {      const url = countryMap[country];      // Remove this logging statement from your final output.      console.log(        `Based on ${country}-based request, your user would go to ${url}.`,      );      return Response.redirect(url);
      // If request country not in map, return another page.    } else {      return fetch("https://example.com", request);    }  },};
