title: ArcGis Connection Error using RestSharp
body: <p>I'm trying to connect to ArcGis to geocode an address to a lat/long, from an Xamarin.iOS app.  I'm initiating the request using this manner:</p>
  
  <pre><code>var request = new RestRequest ("arcgis/rest/services/World/GeocodeServer/find?f=pjson&amp;text=380+New+York+Street+Redlands+CA+92373", Method.POST);
  request.AddParameter ("content-type", "application/json");
  
  var client = new RestClient("http://geocode.arcgis.com/");
  var response = client.Execute (request);
  var jsonOutput = response.Content;
  </code></pre>
  
  <p>However, it always returns blank, and gives me the error "Invalid Cookie Domain: geocode.arcgis.com".  Why is this error happening?  I can't figure this out...</p>
