angular 2 http withCredentials : <p>I'm am trying to use withCredentials to send a cookie along to my service but can't find out how to implement it.
The docs say "If the server requires user credentials, we'll enable them in the request headers" With no examples.
I have tried several different ways but it still will not send my cookie.
Here is my code so far.</p>

<pre><code>private systemConnect(token) {
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    headers.append('X-CSRF-Token', token.token);
    let options = new RequestOptions({ headers: headers });
    this.http.post(this.connectUrl, { withCredentials: true }, options).map(res =&gt; res.json())
    .subscribe(uid =&gt; {
        console.log(uid);
    });
}
</code></pre>
