title: NTML Headers don't get send by Firefox or IE
body: <p>I'm currently developing an ASP.NET App and I want to get the Username &amp; Workstation of the current User/Request.<br>
  I want to use NTLM and the <code>Authorization</code> with the <code>WWW-Authenticate: NTLM</code> HTTP-Headers.</p>
  
  <p>I've enabled these settings in Firefox 4:</p>
  
  <pre><code>network.negotiate-auth.trusted-uris = http://localhost
  network.negotiate-auth.delegation-uris = http://localhost
  network.automatic-ntlm-auth.trusted-uris = http://localhost
  network.ntlm.send-lm-response = true
  </code></pre>
  
  <p>But I don't get the Authorization Header in Firebug or in my app (using <code>Request.Headers</code>).<br>
  I've also tried with IE 9, but it doesn't send it either.</p>
  
  <p>Am I missing something here?</p>
  
  <p>I thought they get send automatically with each request once I've enabled it for the trusted uris and they are send automatically in IE, too, at least in intranets.</p>
  
  <p>The ASP app uses forms authentication and it should stay this way as a fallback.</p>
