Description (partial)

Symptom:
Anyconnect vpn client pops up to notify customer that captive portal has been detected with the below message even that the user does not start or connect using the Anyconnect VPN client.
"You may need to use a browser to gain access."

Conditions:
After any change in the Interface state on the PC https probes are initiated for captive portal detection by the Anyconnect client.
When these probes get redirected, the Anyconnect client concludes that Captive portal is detected and notifies the user by popping up the Anyconnect client with a message. 

On Dart the below logs will be seen.
