Developers who are building Ajax based websites for mobile access have to think of optimization at all times. Even though the performance of mobile computers such as smart phones and UMPCs has increased, their hardware capabilities are still not at par with the experience of a regular computer. Although we are not expecting a desktop-like experience from smart phones, developers should aim for a near desktop experience even for mobile browsing.

There are two ways in developing Ajax in terms of coding principles. Developers could either use the tradition DOM as they would work with JavaScript or they could develop Ajax through OO (object oriented) coding which is usually favorable for developing Ajax.

Mobile devices are limited in connection not only in their hardware capability but also in network connection. Places without any WiFi cannot easily connect online because EDGE, HSDPA or 3G might not be able to handle the connection properly. Ajax based applications needs a lot more than a simple dial-up connection.

Ajax in mobile devices is definitely a challenge for developers. Even with the reduced bandwidth requirements, the presence of JavaScript and the continuous streaming of information could easily take its toll on the mobile device. If the developer is unable to move past this challenge, the possibility of effectively browsing an Ajax based application for mobile browsers could be a little bit challenging.

When iPhone was released, it signaled something revolutionary for mobile phones: Instead of being limited by the pocket versions of browsers, users of mobile devices can experience full website interaction because regular browsers are not installed in their mobile devices. Using Wifi, users will feel they are actually using a laptop in a miniature level.

Dojo is a very powerful framework for developing Web 2.0 and Ajax based websites. Through proper usage of the toolkit, developers should be able to build an Ajax based website with little to no use of JavaScript. But let’s face it – if you want to build a highly efficient Ajax based application using this framework, you should have at least a small amount of JavaScript coding.

Caching Ajax is a difficult task for developers especially browsers have different interpretation on caching content. Mozilla could easily cache streamed content of an Ajax based website. On the other hand IE has issues in caching since information might be continuously cache which will eventually cripple the website. Developers have pushed their coding a little bit more so that website could be loaded effectively in IE.

Reflows in an Ajax application should be minimized as much as possible so that data flow will be controlled and bandwidth will be minimized. Developers have to look out for this type of behavior in their Ajax application since it could happen since the application streams information asynchronously and continuously.

Regular expressions or regexp, is a simple yet powerful function that could be added in an Ajax application. With regexp developers could build a powerful search engine within the application. With this function the search engine could execute faster and be more precise. Usually, developers could just place a simple search function within the Ajax applicantion but it is not optimized since the search results is not that interactive with the user

Conditional preloading is a smart way of providing information to the user. Searching for information could be hastened when conditional preloading is activated since information is gradually made available for the user as the users key-in the data they are looking for.
