title: Convert HttpRequestMessage to HttpRequest
body: <p>I'm converting ASP.NET web application to MVC Web Api project.
  One of my methods expects <code>HttpRequest</code> class. However, Web Api controller holds only <code>HttpRequestMessage</code> (<code>this.Request</code>) object.
  Do you know how I can convert <code>HttpRequestMessage</code> to <code>HttpRequest</code>?</p>
