I try to post parameter like
 jQuery.ajax(
        {
            'type': 'POST',
            'url': url,
            'contentType': 'application/json',
            'data': "{content:'xxx'}",
            'dataType': 'json',
            'success': rateReviewResult 
        }
    );
However, Django return Forbidden 403. CSRF verification failed. Request aborted. I am using 'django.middleware.csrf.CsrfViewMiddleware' and couldn't find how I can prevent this problem without compromising security.
