+[AJAX][] is a web-buzzword that I had always thought must be more
+complicated than it really is. I finally got a chance to look into it
+and write up a simple [[example]]. The example
+
+[[!inline pagenames="example" template="raw" feeds="no"]]
+
+accesses the server-side
+
+[[!inline pagenames="data.xml" template="raw" feeds="no"]]
+
+via
+
+[[!inline pagenames="lookup.php" template="raw" feeds="no"]]
+
+[AJAX]: http://en.wikipedia.org/wiki/Ajax_(programming)
