Hi Guys,
I used an example from adobe.com to make a spry scoreboard that automatically updates the scores from an xml document. I took it futher and have had some success, but when I put it live I found out that it will not update in internet explorer unless clearing history, or opening a new tab then going back.
It works great in firefox and safari, and will update as soon as I change the xml, then upload to my server. Any help would be greatly appreciated. I have searched long and hard for a solution, and it looks like I.E caching may be the culprit. How to get around this though I do not know.
I have put up the demo files from the example as it has the same issue regarding I.E
Thank you!!
Rich

I got some fantastic help on the adobe forums and it's now working great. This was Fabio's answer:
"I solved it adding this bit of code : method:'POST' as in the example below. -
var live_status = new Spry.Data.XMLDataSet("feeds/feed_presence2.xml", "root/row", {useCache:false,loadInterval: 200000, method:'POST'})
-
According to what I read in this forum, using POST will force IE to not cache the data.
Hope it helps."
