What it is:

"Captive Portal is a technique which forces client PC to see a web page 
(usually for authentification) before surfing the Internet normally. You 
will see Captive Portal in most WiFi Hotspot. It can be used to control 
wired access (e.g. Apartment Houses, business center, "open" Ethernet 
jacks) as well."
