Hi Erez,
At the risk of needlessly reiterating some detail:

In cases I've encountered, the alerts seemed to be  OS generated, (done by
OS rather by the site/AP you connected to).
Microsoft does the same thing with the "additional credentials may be
required" pop-up on its Windows OS.

The OS "gets" the fact that an IP address was acquired on an interface, but
- no full 'www' access is available, rather an access to a single web-page
(i.e a captive portal).  The alert is helpful for folks who assume that (IP
address == www access) at any time, and try to place a skype call, or pull
email, and get frustrated with 'it not working'.
I've configured a Captive portal on a proprietary system, not long ago, for
deployment, so I cannot be 100% sure if there's any type of messaging from
the AP to the OS informing it that it's captivated, or, as I mentioned, the
entire wisdom in within the OS' network stack.
