<p>I'm trying to use the new Fetch API and I'm having trouble handling cookies. Specifically, after a successful login, there is a Cookie header in future requests, but Fetch seems to ignore this header and all requests I make using Fetch are unauthorized. </p> <p>Is this because Fetch is not ready yet, or does Fetch not support Cookies? </p> <p>I use Webpack to build my application. I'm also using Fetch in React Native and don't have the same problem. </p>

fetch(url, {
  method: 'GET',
  credentials: 'include'
})
  .then((response) => response.json())
  .then((json) => {
    console.log('Gotcha');
  }).catch((err) => {
    console.log(err);
});

fetch(url, {
  credentials: "same-origin"
}).then(...).catch(...);
