Summary

Ajax can help make your browser-based applications appear faster and more like desktop applications. It requires a working knowledge of JavaScript and may cause a few more debugging headaches, but it can create a dynamic view of your application that results in more productive, happier clients. The benefits for clients who access your Web application over slower connections are even greater, because these clients can appreciate the reduced round-tripping. For larger Ajax implementations, you can look at a pre-existing Ajax library, or you can roll your own (everyone else has, it seems).
