title: Display all messageHeader's values
body: <p>I'd like to know what is the best way to display all MessageHeaders server side. Actually the only way I know is the following:</p>
  
  <pre><code>OperationContext.Current.IncomingMessageHeaders.GetHeader&lt;T&gt;(Name, Namespace)
  </code></pre>
  
  <p>That method is only for a known MessageHeader but I'd like to display their values in a loop.</p>
  
  <p>Thank You</p>
