*
* (String) url - The URL of the page to request.
- *
- * (String) data - A string of data to be sent to the server (POST only).
+ *
*
* (String) dataType - The type of data that you're expecting back from
* the server (e.g. "xml", "html", "script", or "json").
* function gets passed two arguments: The XMLHttpRequest object and a
* string describing the type the success of the request.
*
+ * (String) data - Data to be sent to the server. Converted to a query
+ * string, if not already a string. Is appended to the url for GET-requests.
+ * Override processData option to prevent processing.
+ *
+ * (String) contentType - When sending data to the server, use this content-type,
