Blocks certain countries from accessing your page, while giving the flexibility to whitelist certain paths.
addEventListener('fetch', event => {
async function byPassOrBlock(request) {
let url = new URL(request.url)
let blockedCountries = ['XX']
let whitelistedPaths = ['/about*']
for (let i=0; i<whitelistedPaths.length; i++) {
if (new RegExp("^" + whitelistedPaths[i].split("*").join(".*") + "$").test(url.pathname)) {
return fetch(request)
if (blockedCountries.includes(request.headers.get('cf-ipcountry'))) {
// Return a Forbidden response
return new Response('Sorry, this page is not available.', { status: 403, statusText: 'Forbidden' })
// Or, alternatively, return a redirect. Make sure to whitelist this to avoid loops
// return Response.redirect('')
return fetch(request)
