i have followed this example to try to trace the itinerary between two points :
http://developers.cloudmade.com/projects/routing-http-api/examples
However in the example there is no notification of where to put the http query : http://routes.cloudmade.com/YOUR-API-KEY-GOES-HERE/api/0.3/start_point,[[transit_point1,…,transit_pointN]],end_point/route_type[/route_type_modifier].output_format[?lang=(en|de)][&units=(km|miles)]
Any help will be appreciated.
