ajax tabs 1.10

ajax tabs 1.10

I want to be sure I am understanding the new ui tabs and how it handles ajax requests.  I have a list of data records in one tab and when a user clicks on a link from a record in that list I want to switch to my tab that shows the detailed information for the specific item (so a list tab and a detail tab). I was hoping to use ajaxSettings.data, but if I'm following the discussion for ticket 8673 correctly, I need to change ajaxSettings.url with the data attached as a querystring.   Tabs beforeload returns ui.ajaxSettings but it is not the full jquery core ajax settings. Am I understanding correctly?
