For Django CSRF token protection
fileDownload need add csrftoken parameter
currently, you just need add correct csrf value to do it

Example:

$.fileDownload(url, {
    httpMethod: "POST",
    csrfmiddlewaretoken: "{{csrf_token}}",
    parameter: your_paramter,
})

There's a problem with iPad and django (1.11.6) on POST requests.

It seems Safari is not setting/sending the document.referrer, so the CsrfViewMiddleware will reject the request with error 403 because it suspects about a man-in-the-middle attack.

fileDownload when dealing with isIos devices opens a new window.
