301 Redirect

This example demonstrates how to use the HTTP 301 status code to automatically and permanently redirect client requests to a preset website address. It is commonly used for permanent site migration or merging.

Sample Code

// Target redirect address
const destinationLocation = 'https://www.example.com';

// HTTP status code, used for permanent redirects
const statusCode = 301;

// Async function used to handle requests
async function handleRequest(request) {
// Return a redirect response with the specified target location and status code.
return Response.redirect(destinationLocation, statusCode);
}

// Add a fetch event listener to intercept requests and respond using the handleRequest function.
addEventListener("fetch", event => {
event.respondWith(handleRequest(event.request));
});

Sample Preview

In the address bar of the browser, enter a URL that matches a triggering rule of the edge function to preview the effect of the sample code.
