title: Sending multipart/mixed content with Postman Chrome extension
body: <p>I'm struggling with creating POST multipart/mixed request with Postman Chrome extension</p>
  
  <p>Here is my curl request what works nice</p>
  
  <pre><code>curl -H "Content-Type: multipart/mixed" 
  -F "metadata=@simple_json.json; type=application/json "
  -F "content=@1.jpg; type=image/jpg" -X POST http://my/api/item -i -v
  </code></pre>
  
  <p>interesting part of response</p>
  
  <blockquote>
    <p>Content-Length: 41557</p>
    
    <p>Expect: 100-continue</p>
    
    <p>Content-Type: multipart/mixed; boundary=----------------------------8aaca457e117</p>
    
    <ul>
    <li>additional stuff not fine transfer.c:1037: 0 0</li>
    <li>HTTP 1.1 or later with persistent connection, pipelining supported</li>
    </ul>
  </blockquote>
  
  <p>And when I use Postman
  <img src="https://i.stack.imgur.com/0fTmX.png" alt="enter image description here"></p>
  
  <p>I getting such response</p>
  
  <pre><code>{"message":"Could not parse multipart servlet request;
   nested exception is org.apache.commons.fileupload.FileUploadException: 
   the request was rejected because no multipart boundary was     
   found","type":"error","status":500,"requestId":"1861eloo6fpio"}
  </code></pre>
  
  <p>That's it - I wish to get rid of that error.
  If some more information needed please ask :)</p>
