title: Downloading website html content using WebClient issues a 407 response, why?
body: <pre><code>public const string url = 
  "http://www.londonstockexchange.com/exchange/prices-and-markets/international-markets/indices/home/ftse-mib.html";
  
  public static void Main(String[] args)
  {
      WebClient wc = new WebClient();
      string s = wc.DownloadString(url);
  }
  </code></pre>
  
  <p>When I run this code I get the error message: The remote server returned an error: (407) Proxy Authentication Required. I have no idea what to do, can someone give me some advice?</p>
