title: JsonServiceClient Posting File with Parameters and Custom Header
body: <p>All,</p>
  
  <p>We are trying to post files with data using the latest V3 version of SS, and have finally achieved success with one exception. We are still unable to send a custom header along with the data. Here is what we are trying to post in the header, but it never exists in the header when the request arrives at my SS instance.</p>
  
  <pre><code>client.LocalHttpWebRequestFilter = x =&gt; { 
      x.Headers.Add("Authorization-KAPI", AuthorizationKAPI); 
  };
  </code></pre>
  
  <p>Suggestions please?!?!</p>
  
  <p>Thanks,
  B</p>
