title: WebChannelFactory & Headers?
body: <p>Is it possible to set headers on a <code>WebChannelFactory</code>? If I were using a <code>WebClient</code> object, I could do something like this:</p>
  
  <pre><code>WebClient client = new WebClient();
  client.Headers.Add("referer", "http://stackoverflow.com");
  client.Headers.Add("user-agent", "Mozilla/5.0");
  </code></pre>
  
  <p>But I haven't been able to figure out a way to modify the headers on a <code>WebChannelFactory</code>.</p>
