A while back, I discovered a neat little trick to update a web page without going for a complete page reload. This kind of discovery is akin to stumbling over a solid gold yacht. Naturally, I wasn’t the only person to ever discover what would later dubbed AJAX, but it was new to me. Anyway, I’ve had a great number of successes with the technique and I feel I’ve finally mastered the intricacies of the technique. It feels good.
For a good example of ajax, checkout Google Maps.
