Wait, you're saying if I can control that URL I can prevent all iOS devices in the world from connecting to the Internet ? That sounds seriously dangerous. Or am I mis-understanding?

If you can control that URL, you can probably control ANY URL, and thus you can already prevent any (not just iOS) devices from connecting to the internet _via your wifi ap_. No surprises there. iOS falls back to 3G when the page doesn't respond as expected.

      There's a large enough proportion of them connecting to wifi networks at a given time and a very large number of devices. Plus it's a very small static page.
