WEB.API DataSource Cross Domain with Authentication Header

[Dustin]

Is it possible to use WEB.API as the datasource when its cross domain and needs an Authorization header set?

I know you can do cross domain with jsonp, but I read in another thread that with jsonp you can't use the beforeSend - setRequestHeader.

var aumData = new kendo.data.DataSource({
                   transport: {
                       read: {
                           url: '<%=Common.GetAppSetting("WebApiBaseUrl") %>Portfolio/Clients/Value',
                           dataType: "jsonp",
                           beforeSend: function (req) {
                               req.setRequestHeader("Authorization", "<%= this.webApiToken %>");
                           }
                       }
                   }
                });

Hello,

 Indeed JSONP cannot set HTTP headers. You need to use JSON request which requires additional configuration to work cross-domain and won't work in all browsers. More info can be found here.
