	//		the site has full access to your JavaScript environment.
	//	url:
	//		Url prefix of the site which can handle JSONP requests.
	// 	httpAdapter: This allows for adapting HTTP requests that could not otherwise be
	// 		sent with JSONP, so you can use a convention for headers and PUT/DELETE methods.
