title: stop $resource from encoding URL
body: <p>Working on a a routing system using OSRM.  Right now I'm encoding my coordinates as a polyline, but the polyline keeps getting URL encoded before it gets send to the server so it's not sending the correct polyline definition.  </p>
  
  <p>Is there a way to keep my url from being URL encoded</p>
