Enables the ‘jsonpi’ dataType parameter for $.ajax.
What the hell is JSONPI?
A pattern for making AJAX-like requests across subdomains. Since browsers block XmlHttpRequest across subdomains (because they have different Origins), JSONPI is a workaround that uses iframes, forms, and document.domain to achieve the same effect. Unlike JSONP, JSONPI permits the use of HTTP POSTs. See Usage for more information.
