just wondering if anyone knows how some of these commercial hotspots (such as tmobile in starbucks or in the 4star hotels) are able to automatically redirect the user's browerser to a specific ip webhost page to login to the hotspot network for internet usage.
i know they use some javascript to redirect the user... but how do they even redirect any/all traffic from the new user who hasn't logged in to the hotspot's login page?
anyone know?
thanks! Kram
