Sending ajax requests in batch of 3 or 5

Question

I am in asp.net mvc paradigm. On one of my views, I have two fields Start Number and End Number. User is allowed to enter numeric values in these fields and when he clicks on submit button I have to loop from startNumber to endNumber and send an ajax requests for each iteration of the loop.

I have a scenario when the difference between start number and end number may range to 100's, so I am planning to send ajax requests in batch of 3 or 5. e.g I will send three requests and wait for them to complete and after that, I need to send next three until the loop is completed. I don't know how to target this problem.

Instead of hammering your server with multiple AJAX request I'd recommend you send a single AJAX request containing all the necessary information. This will be more efficient rather than sending multiple requests with smaller payload.

Yes, In ordinary circumstances it is desireable to bundle ajax requests but in this case if I send all the necessary data in one or even 2 or 3 requests they might time out or at best user will have to wait more than a minute or two to see the response. – Muhammad Adeel Zahid Feb 20 '13 at 16:49

Create batch of 3 or 4 requests, and use below sample code which detect AJAX requests comepletes or not.

$( ".log" ).ajaxStop(function() {
  $(this).text( "Triggered ajaxStop handler." );
});

After comeleting all request,call another batch.
