title: Laravel 5.1 xmlHttpRequest AJAX POST TokenMismatchException
body: <p>The relevant code is shown below:</p>
  
  <pre><code>var csrfToken = "{{ csrf_token() }}";
  xmlhttp.open("POST", "/internal/v1/create/strategy", true);
  xmlhttp.setRequestHeader('X-CSRF-TOKEN', csrfToken);
  postString = "param1=" + varOne + "&amp;param2=" + varTwo;
  xmlhttp.send(postString);
  </code></pre>
  
  <p>I've been trying to figure this out for hours now, I honestly have no idea what to do at this point. Note, that if I use the form method everything works just fine. I've also tried sending the CSRF token as a parameter in the postString: "_token=" + csrfToken</p>
