While the asynchronous nature of Ajax applications makes them fundamentally different from standard Web applications Ajax applications are still built upon standard Web infrastructure. Moreover this asynchronous behavior does not obviate the benefits of solutions like the Citrix NetScaler. Indeed this asynchronous behavior can make NetScaler's Request Switching and high-availability functionality more important to an Ajax application than to a standard Web application. Finally NetScaler will speed up the initial load of an Ajax application and helps ensure that the perceived user experience benefits of asynchronous communication are not thwarted by network and server delays.
