Yesterday, I found that people are actually using my ages old XMLHttpRequest script. At least, that's how some people end up on this blog - after googling for "Jasper's HttpRequest script".
Well, it's quite old and uses techniques for compatibility with older browser which basically have been given up on today (IE 6). Still, I think the thing should still work. But it wasn't hosted anywhere, so now is my chance to fix that. Here's an all-new link to the script: link.
I do want to revisit the script some time and update it and all and perhaps it will even some day be integrated into GoodLooking. Until that time, feel free to use the script from the link above. There is one thing I do ask you for, though. I would like it if you let me know what you are using the script for. Just out of curiosity, really.
