        //              is *not* a secure transport, by loading data from a third-party site using JSONP
        //              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.
