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. -- Guy Gold
