Html extension. A web application developer has to know XHTML, CSS, JavaScript, XML, and the Document Object Model (DOM) at a minimum. Most developers also know Extensible Stylesheet Language Transformation (XSLT), and syndication techniques. And remember, this is just the client side of things. In Chapter 3, we will explore the other side of Ajax, which is the server side. A developer should also understand how the HTTP server works, one or more server-side scripting languages, and databases. Web applications require developers to know a wider variety of things than a desktop application developer would ever need to know.

Take a look at Appendix D for risks that Ajax can create. I love the Ajax model of design; I think it brings web applications closer to the capabilities of desktop applications. I also know, somewhat from experience, that Ajax is not the best solution for every project, and that it can sometimes overcomplicate what could have been a simple solution. As you read the rest of this book and you see Ajax solutions that I present to common web design issues, ask yourself whether Ajax is right for you and what you are trying to accomplish.

The Developer | 33 What Ajax Is Not Ajax is not the be-all and end-all solution to every new application being built for the Web. It is not even something that should be considered as an upgrade to every existing product. 0 applications, but only when they are built correctly. Throwing Ajax at every application can create complications, such as accessibility issues, cross-browser compliance nightmares, and requiring more intricate and complex programming to perform simple tasks.
