A few weeks back I had the awesome opportunity to speak at the jQuery Conference in Boston. A colleague, Boaz Sender, encouraged me to propose a topic, but I couldn’t help wondering, “What could a dojo enthusiast possibly speak about at a jQuery conference?”

It’s no secret that one of the keys to a decent user experience is a responsive (fast) user interface. And the most critical component to a fast web app is minimizing the HTTP requests. So it’s no mystery that people are working on ways to solve this problem.
Firefox, of course, is one of the leaders in this area. Their proposal started out fine. Here’s a sample of what it would look like (if you didn’t read the article):
