Aborting chains of Ajax calls in Javascript

Sometimes when the user triggers the same event more than once, the same Ajax call is made multiple times. Its pretty straight forward to setup a simple object to keep track of identical calls and abort the oldest ones, but how can I deal with this when there are chains of calls made?

What do I mean with chains: Lets say user clicks a button and that triggers ajax_A(...). At some later point ajax_B(...) is also executed. At this point the user clicks the same button again which invokes the same chain again.

Is there a practical way of aborting the whole chain (both ajax_A(...) and ajax_B(...))?

Our current solution is quite obtrusive for those sections where we make an ajax call that is part of a chain.
