are you telling me that (in the case of starbucks) every hotspot at a
starbucks is running a computer/server at their location JUST for
redirecting all the traffic to a specific logon page? i always thot it
was a special router of some sort... so every hotspot that redirects
traffic is using a server?

Hello...
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?
Capture all TCP traffic to port 80. Intercept locally (most of the
"free" operating systems have facilities to do this) in a web server
which sends a "302 Page Moved" with the new URL back to the client.
