I have a XHTML page that I am using for a digital signage display. I have flash content with a stock and weather feed on the page. I am bringing the stock and weather feed in using an iFrame so I can have those sections refresh every half an hour. I want to be able to disable the stock from refreshing after a certain at night and then start back up again in the morning at a certain time. Does anyone have any ideas for this? I would like the stock to stop at 5PM and start around 7AM.
