export function is_form_content_type(request) {
	// These content types must be protected against CSRF
	// https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement/enctype
	return is_content_type(
		request,
		'application/x-www-form-urlencoded',
		'multipart/form-data',
		'text/plain'
	);
}
