Slincing huge amount of requests in chunks and Deferring jQuery AJAX requests to execute a chunk at time.
Let's say, that you have a ton of ajax requests to do (what's not recomended) and parallelize all requests may turn your server unstable and your screen blocked.
In this gist I document a solution that I used to preserve the server's sake and alleviate page loading.
So, we have elements that holds an attribute (data-async-url) that prior this kludgy solution was used by the jquery plugin async-include by Mr. Peter Coles. BTW, Thanks, Peter!
