title: Is Content-Disposition required for a multipart/form-data HTTP POST?
body: <p>What if I'm just sending an array of images in no particular order, i.e., the <code>name</code> field doesn't matter, and I just want the server to determine the <code>filename</code> arbitrarily?</p>
  
  <p>Must I send <code>Content-Disposition</code> for each file?</p>
