Add Headers to a Response

You can use this document to learn how to add additional headers to your request, such as additional cookies. 

In the following example, the route is: cookie-test

Review the following sample script:

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

async function fetchAndApply(request) {
  const response = await fetch(request);

  const modifiedHeaders = new Headers(response.headers);

  modifiedHeaders.append("Set-Cookie", "Value 1");
  modifiedHeaders.append("Set-Cookie", "Value 2");

  const init = {
    status: response.status,
    statusText: response.statusText,
    headers: modifiedHeaders
  };

 const modifiedResponse = new Response(response.body, init);
 return modifiedResponse;
}

You can access your script with any of the Delivery Domains on your account.

Based on the above example, you can access the script with: https://domain.com/cookie-test
