jQuery.ajaxQueue
A simple jQuery plugin to allow queueing of ajax requests so they are fired consecutively, rather than in parallel. A request can optionally be labelled, and only one instance of each label will be added to the queue. If a request with a matching label exists in the queue, it will be moved to the end.
Test suite notes
testopts{} and badopts{} in the test suite need to be a working and broken request for the test suite to function properly.
