title: new FormData() "application/x-www-form-urlencoded"
body: <p>Couchdb only parse application/x-www-form-urlencoded. Is there a FormData() attribute that set the enctype?</p>
  
  <pre><code>xhr.open('put',document.myForm.action,false)
  xhr.setRequestHeader('Content-Type','application/x-www-form-urlencoded')
  xhr.send(new FormData(document.myForm))
  </code></pre>
