Sean’s recent article about using SAJAX was published at IBM today. He constructs a simple photo viewer application using an XML file for meta data about each photo. PHP and the SAJAX (Simple AJAX) toolkit are used to present the images.

In my follow up article, part 2 in the series, I describe how you can use client-side JavaScript to implement a history cache for the application that mimics the history utility in web browser software. Many AJAX applications suffer from the lack of “undo” functionality, or history navigation, that normal web browsing employs. That’s what I will be addressing. However, the solution will not involve hijacking the back button as other developers have demonstrated. Instead, it shows how to track a history of events using JavaScript within a single browsing session.
