Can AJAX cause “Denial of Service”?

For instance, Google Suggest may fire off a tiny HTTP request for each user keystroke in an attempt to perform automatic word completion. The assumption is that if there are 1,000 users on the system, moving to the AJAX rapid-fire model will exponentially increase the number of requests to the system. This could potentially result in a denial of service (DoS) scenario. I suppose this is possible, but whose fault is this really? In my view, this problem is not caused by AJAX or even a bad software design strategy, but instead by a lack of proper implementation and performance testing. The solution is to tune the configuration or add more web servers. And to be realistic, if someone wanted to DoS a network, they could flood the network with HTTP traffic whether AJAX was used or not. Does AJAX rely on clie
