Performing Redirect Based on the Request Location

This example implements automatic redirection to the Target url of the region belonging to the Client by judging the region of the Client. It realizes the delivery of requests based on the region of the Client through Edge functions.

Sample Code

// The collection of URLs in all regions.
const urls = {
CN: 'https://www.example.com/zh-CN',
US: 'https://www.example.com/en-US',

// The default redirect URL.
const defaultUrl = 'https://www.example.com/en-US';

* Redirect to the target URL based on the region of the current request.
* @param { Request } request
function handleRequest(request) {
// Obtain the region of the current request.
const alpha2code = request.eo.geo.countryCodeAlpha2;
// The target URL that you want to use for redirection.
const url = urls[alpha2code] || defaultUrl;

return Response.redirect(url, 302);

addEventListener('fetch', event => {
