As I understand so far, AJAX is basically a pulling mechanism for updating web pages dynamically. Is it possible to use pushing instead of pulling in AJAX?
Also I have seen some web applications using AJAX to pull the server every 2 seconds. In this case if the server keeps the http connection alive does it mean the user will occupy one connection channel over the whole session?
My other concern of using AJAX is its impact of the scalability and availability on the web server. It seems AJAX will increase much more workload on the server and network as well. Can we discuss this topic deeper?
