* (String) dataType - The type of data that you're expecting back from
* the server (e.g. "xml", "html", "script", or "json").
*
+ * (Boolean) ifModified - Allow the request to be successful only if the
+ * response has changed since the last request, default is false, ignoring
+ * the Last-Modified header
+ *
+ * (Number) timeout - Local timeout to override global timeout, eg. to give a
+ * single request a longer timeout while all others timeout after 1 seconds,
+ * see $.ajaxTimeout
+ *
+ * (Boolean) global - Wheather to trigger global AJAX event handlers for
+ * this request, default is true. Set to true to prevent that global handlers
+ * like ajaxStart or ajaxStop are triggered.
+ *
* (Function) error - A function to be called if the request fails. The
* function gets passed two arguments: The XMLHttpRequest object and a
* string describing the type of error that occurred.
