title: finding content-type from wireshark
body: <p>Here are the wireshark logs of 3 POST's. All posting the same data but with different content-types, resulting in different ways the data is read on the server. I'm attempt to to understand how to create POST Z.</p>
  
  <p><strong>POST X</strong>
  Explicitly setting form based post </p>
  
  <p><img src="https://i.stack.imgur.com/GUELA.png" alt="enter image description here"></p>
  
  <p>gives <img src="https://i.stack.imgur.com/lCZxN.png" alt="enter image description here"></p>
  
  <p><strong>POST Y</strong>
  Omitted content-type</p>
  
  <p><img src="https://i.stack.imgur.com/PdFhP.png" alt="enter image description here"></p>
  
  <p>gives <img src="https://i.stack.imgur.com/e1Xd3.png" alt="enter image description here"></p>
  
  <p><strong>POST Z</strong> ?
  My app is not able to reproduce this.</p>

  <p>gives <img src="https://i.stack.imgur.com/2hmAP.png" alt="enter image description here"></p>
  
  <p>I'm attempting to guess what content-type in the last POST Z (notice there are no brackets), which made the post parameters appear as data ( and apparently without a data-type )</p>
  
  <p>Thanks
