I've always wondered how Android (and Windows) "know" whether you're
connected to the internet or not. I guess what you say make sense. Is
this documented somewhere? Is there a way to change the HTTP request to
some other host of your choosing?

For Windows (Vista), we find some documentation here:

Is there anything like this pre-made for Debian? I suppose it would be
easy enough to script.
