set withCredentials to the new ES6 built-in HTTP request API : Fetch
<p>How to set <code>withCredentials=true</code> to  <a href="https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch" rel="noreferrer"><code>fetch</code></a> which return promise.
Is the following correct : </p>

<pre><code>fetch(url,{
   method:'post',
   headers,
   withCredentials: true
});
</code></pre>

<p>I think the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch" rel="noreferrer">MDN documentation</a> talked about everything about http-requesting except this point: <code>withCredentials</code> </p>
