title: Randomly seeing System.NotSupportedException: http in WebRequest.GetCreator(string prefix)
body: <p>On our ASP MVC application running on mono, we sometimes get this NotSupportedException: http when creating WebRequests.
  Here is the stacktrace:</p>
  
  <pre><code>979: Message: System.NotSupportedException: http
