POX based Autodiscover clients and the Exchange 2013/Office365 preview

The big thing is the past week or so has been the release of the Exchange 2013 preview and in the cloud world the Office365 (Exchange Online 2013) preview. One of the new things in the Auto-discover response if your using one of these is the EXHTTP node that gets returned eg


I haven't quite found where this node is documented yet but if your creating Outlook Anywhere Profiles programmatically against the Office365 preview then the Server info from this node is important for building a Outlook Anywhere profile.  If your using your own POX based Auto-discover client you won't get access to this new information unless you set the UserAgent so the request looks likes its coming from Outlook.
eg

  1. String snServerName = @"https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml";  
  2. String OAProxy = "";  
  3. String OAProxy1 = "";  
  4. String ProxyCertName = "";  
  5. String ProxyCertName1 = "";  
  6. String ProfileName = "";  
  7. String InternalServerName = "";  
  8. //Do AutoDiscover  
  9.   
  10. String auDisXML = "<?xml version=\"1.0\" encoding=\"utf-8\"?><Autodiscover xmlns=\"http://schemas.microsoft.com/exchange/autodiscover/outlook/requestschema/2006\"><Request>" +  
  11.       "<EMailAddress>" + emEmailAddress + "</EMailAddress>" +  
  12.       "<AcceptableResponseSchema>http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a</AcceptableResponseSchema>" +  
  13.       "</Request>" +  
  14.       "</Autodiscover>";  
  15. System.Net.HttpWebRequest adAutoDiscoRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(snServerName);  
  16. adAutoDiscoRequest.CookieContainer = new CookieContainer();  
  17. NetworkCredential ncCred = Credential;  
  18. byte[] bytes = Encoding.UTF8.GetBytes(auDisXML);  
  19. adAutoDiscoRequest.ContentLength = bytes.Length;  
  20. adAutoDiscoRequest.ContentType = "text/xml";  
  21. adAutoDiscoRequest.UserAgent = "Microsoft Office/14.0 (Windows NT 0.0; Microsoft Outlook 14.0.6112; Pro)";  
  22. adAutoDiscoRequest.Method = "POST";  
  23. adAutoDiscoRequest.Credentials = ncCred;  
  24. CookieContainer svccook = adAutoDiscoRequest.CookieContainer;  
  25. System.IO.Stream rsRequestStream = adAutoDiscoRequest.GetRequestStream();  
  26. rsRequestStream.Write(bytes, 0, bytes.Length);  
  27. rsRequestStream.Close();  
  28. adAutoDiscoRequest.AllowAutoRedirect = false;  
  29. WebResponse adResponse = adAutoDiscoRequest.GetResponse();  
  30. String Redirect = adResponse.Headers.Get("Location");  
  31. if (Redirect != null)  
  32. {  
  33.     adAutoDiscoRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(Redirect);  
  34.     adAutoDiscoRequest.ContentType = "text/xml";  
  35.     adAutoDiscoRequest.ContentLength = bytes.Length;  
  36.     adAutoDiscoRequest.Headers.Add("Depth""0");  
  37.     adAutoDiscoRequest.UserAgent = "Microsoft Office/14.0 (Windows NT 6.1; Microsoft Outlook 14.0.6112; Pro)";  
  38.     adAutoDiscoRequest.Method = "POST";  
  39.     adAutoDiscoRequest.Credentials = ncCred;  
  40.     rsRequestStream = adAutoDiscoRequest.GetRequestStream();  
  41.     rsRequestStream.Write(bytes, 0, bytes.Length);  
  42.     rsRequestStream.Close();  
  43. }  
  44. adResponse = adAutoDiscoRequest.GetResponse();  
  45. System.IO.Stream rsResponseStream = adResponse.GetResponseStream();  
  46. XmlDocument reResponseDoc = new XmlDocument();
