title: F# Data http request using Windows credentials
body: <p>I'm trying to get some html from a page hosting by IIS where Windows authentication is enabled.</p>
  
  <p>So far I have:</p>
  
  <pre><code>open FSharp.Data
  
  [&lt;EntryPoint&gt;]
  let main argv = 
      let html = Http.RequestString ("http://mywebsite.com/Detail.aspx", query=[("zip","9000");("date","11/01/2017")], headers=[???])
  
      printf "%s" html
      System.Console.ReadLine() |&gt; ignore
      0 // return an integer exit code
  </code></pre>
  
  <p>What do I need to add in the headers list?</p>
