Bulk Redirects

This example redirects requests to specific URLs based on mapped objects.

addEventListener("fetch", (event) => {
    event.respondWith(handleRequest(event.request));
});


async function handleRequest(request) {
  const externalHostname = "edge.examples.com";

  const redirectMap = new Map([
    ["/bulk1", "https://" + externalHostname + "/redirect2"],
    ["/bulk2", "https://" + externalHostname + "/redirect3"],
    ["/bulk3", "https://" + externalHostname + "/redirect4"],
    ["/bulk4", "https://google.com"],
  ]);

  const requestURL = new URL(request.url);
  const path = requestURL.pathname;
  const location = redirectMap.get(path);

  if (location) {
    return Response.redirect(location, 301);
  }
  // If request not in map, return the original request
  return fetch(request);
}
