[jQuery] how do a post-action by default for every ajaxCall success

[oscar esp]

I need to control the expiration time session in order to warning the
user.
I am using settimeout method. In order to update the settimeout I need
to call a method each time that Ajax call has success. I have a lot of
Ajax calls...

I would like execute by default the update timeout for every Ajax
call.

Is there any way to do it using ajaxsetup? Or ... Are there any palace
into jquery code where I could add this call?
