Response with another Site

This example responds to the edge computing request with a response from another website (example.ir in this example).

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

async function handleRequest(request) {
  async function MethodNotAllowed(request) {
    return new Response(`Method ${request.method} not allowed.`, {
      status: 405,
      headers: {
        Allow: "GET",
      },
    });
  }
  // Only GET requests work with this proxy.
  if (request.method !== "GET") return MethodNotAllowed(request);
  return fetch(`https://example.ir`);
}
