No valid Cross Domain Policy with FTPWebRequest

Hi I am using this code to get a list of files on an FTP server which can't be done with WWW class. I have a cross domain xml file on my server and it works fine for the http stuff of downloading files using WWW class but not the FTPWebRequest stuff. I am not sure how to tell Unity to find crossdomain.xml for my FTPWebRequest calls?

 Debug.Log("Attempting to Connect");
 FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://mysite.com/www/Viewer/Projects");
 request.Credentials = new NetworkCredential("user", "password");
 request.Method = "NLST";
 Debug.Log("Getting Response");
 FtpWebResponse response = (FtpWebResponse)request.GetResponse();
 Debug.Log("Getting the Stream");
 
 Stream responseStream = response.GetResponseStream();
 
 StreamReader reader = new StreamReader(responseStream);
 
 while (!reader.EndOfStream)
 {
    string ProjectName = reader.ReadLine();
    ProjectFolders.Add(ProjectName);
    Debug.Log(ProjectName);
 }
 
 reader.Close();
 response.Close();
 
 Debug.Log("Reached End");
