Wifi && connect from Android YourFreedom App (a bit OT)

[Matthias Apitz]

Hello,

I returned last night from Havana, Cuba. They have now Wifi in the
hotels and my FreeBSD netbook (10-CURRENT) connected fine, on start of
WPA you get an IP addr by DHCP and the first page in a browser (FF 24.0)
re-directed you to a page to enter the credentials (login, password for
around 4 USD per hour); a lot of cubans were sitting around with their
laptops and Android based tablets using the Wifi zone of the hotel;

I talked to someone and he said he was using some App 'Your Freedom'
(or something like that) and was not asked for credentials to connect
to his Facebook account, etc. This surprised me a bit, how this could
work technically, and that's why I wanted to ask it here: how this could
bypass the credential page, because I could not route traffic through
the assigned IP on the WLAN interface without passing the credential
page... how this could work with this App? My interest is only
technically or due to the surprise, I do not want to use such trick on
FreeBSD and I do not have any Android device.

Thanks
