[jQuery] Form Plugin: access xhr object


Hi all,
I'm quite new to JQuery and started using the Form Plugin found here:
http://malsup.com/jquery/form/
In my success callback I am trying to get hold of the XmlHttpRequest
instance that was used to make the Ajax request.
However xhr does not seem available from the arguments passed into the
success callback? Looking at JQuery docs the ajax function does return
xhr instance, but how to get access when using the form plugin?
The reason for this is server side returns certain response headers
which I would like to inspect and act upon.
kind regards
bob
