Hi Echonest, I am trying to use your API inside the browser to get information about some tracks. When I call http://developer.echonest.com/api/v4/track/profile with a simple GET request everything works fine. But if I want to modify that request by setting the cache-control header Chrome and Firefox do an OPTIONS request first to check if they are allowed to do that and this request fails. Do you support OPTIONS requests for that endpoint?
