title: HttpWebRequest.Headers[HttpRequestHeader.Referer] failed with error
body: <p>When I'm trying to set Referer header I'm getting the following error:</p>
  
  <pre><code>var request = (HttpWebRequest) WebRequest.Create(url);
  request.Headers[HttpRequestHeader.Referer] = "http://somesite.com/";
  </code></pre>
  
  <blockquote>
    <p>This header must be modified with the appropriate property"</p>
  </blockquote>
  
  <p>But there is no "appropriate" property for Referer.</p>
  
  <p>What could be the reason?</p>
  
  <p>up: I'm using PCL which is referenced by MonoTouch/MonoDroid/WP7.5 projects (Client Profile 104)</p>
