> XMLHttpRequest wasn't a widely known thing yet. (I didn't hear of it until maybe '04 or '05, but it looks like it first appeared in '99?)
My memory says that it was first implemented in IE 5.5, which was released in 2000. Wikipedia says [0] that it first appeared in IE 5.0 but with a different syntax.
