partly OT: notification of url when connecting to open wifi

[E.S. Rosenberg]

re:all
You may not do anything but your system (whether it is android or a desktop
os) tries to ascertain whether or not it has internet connectivity or just
LAN, if it tries to say GET google.com:80 it will get a HTTP/30x from the
wireless gateway redirecting it to a payment/gateway-rules page, since it
"knows" that google.com or whatever it tried to connect to should return a
200 and can read the returned 30x header displaying a notification is then
childs-play.
