Redirect the viewer to a new URL - Amazon CloudFront

Redirect the viewer to a new URL

The following example function generates a response to redirect the viewer to a country-specific URL when the request comes from within a particular country. This function relies on the value of the CloudFront-Viewer-Country header to determine the viewer’s country.

Important

For this function to work, you must configure CloudFront to add the CloudFront-Viewer-Country header to incoming requests by adding it to the allowed headers list in a cache policy.

This example redirects the viewer to a Germany-specific URL when the viewer request comes from Germany. If the viewer request doesn’t come from Germany, the function returns the original, unmodified request.

This is a viewer request function.

See this example on GitHub.

function handler(event) { var request = event.request; var headers = request.headers; var host = request.headers.host.value; var country = 'DE' // Choose a country code var newurl = `https://${host}/de/index.html` // Change the redirect URL to your choice if (headers['cloudfront-viewer-country']) { var countryCode = headers['cloudfront-viewer-country'].value; if (countryCode === country) { var response = { statusCode: 302, statusDescription: 'Found', headers: { "location": { "value": newurl } } } return response; } } return request; }
