Got it working. Thanks Andrew!

I then tried to extend example to Mozilla based browsers with
XMLHttpRequest() API but can't seem to get it to work. Anyone try this?

Also I found that on IE browser is caching data. I have to close &
re-open browser to get updated data. This is not a good feature. Is
there a switch to force a refresh?
