The release there is quite different from the version in svn, which
may be closer to what you are looking for:
http://dev.jquery.com/browser/trunk/plugins/ajaxQueue/jquery.ajaxQueue.js
The docs are all wrong, but the usage is really simple:
No ports:
$.ajax({
mode: "abort"
});
With ports:
$.ajax({
mode: "abort",
port: "autocomplete"
});
Ports are useful when you don't want to cancel everything, but only a
certain type of request, like those for a autocomplete component.
