@Four Feathers: I’m not sure your method addresses the same problem as the one outlined in the article. The technique in the article allows you to return HTML and arbitrary JavaScript from a single XMLHttpRequest.
It appears that your code would have to be embedded in the page that makes the request, not the one returned by it. In which case a callback function (that doesn’t require the use of an image) attached to the onreadystatechange() event handler of the request object is the better solution.
