Windows 7 Network Awareness: How Windows knows it has an Internet connection
Yes, I have wanted to build something like that for Android, mainly to keep my phone from getting confused when it's connected to someone's wifi that demands some check box be checked off for service.<p>It would periodically awaken, see if the wifi is connected, if it is is there connectivity, if there is, go back to sleep, if there is not, turn the wifi off.<p>I've also wanted to build for Android the same piece of code, but if for 2 or 5 urls it gets back the same page with a checkbox, it checks off the box and sends it back off.<p>But I am curious, do all those wifi dns terms and agreements hijacking pages break any sort of RFC?<p>And is there any solution in ip6?<p>Or is there a real fix possible in ip4?
