Editing Captive portal (section)

==Detection==
Captive portal detection URLs typically return a minimal, standardized response when not behind a captive portal. When the device receives the expected response, it concludes that it has direct internet access. If the response is different, the device assumes it is behind a captive portal and triggers the captive portal login process.
