I need to make a jsonp POST request with the content type 'application/json'. I can get the POST request to the server like this:

      jQuery.ajax({

        type: 'POST',

        url: url,

        data: data,

        success: success,

        error: error,

        async: true,

        complete: complete,

        timeout: TIMEOUT,

        scriptCharset: 'UTF-8',

        dataType: 'jsonp',

        jsonp: '_jsonp',

      });

But as soon as I add the line:contentType: application/json it starts sending it as an OPTIONS request rather than a POST.

How can I specify the content type and still submit the request as a POST?
