Opened: May 05, 2014
Severity: 3-Major

Symptoms

The system uses a Microsoft-specific captive portal detection URL (http://www.msftncsi.com/ncsi.txt).

Impact

With this bug we are trying trying to change it to F5 captive portal detection URL (http://www.f5.com/apps/all/avail.txt), and at the same time provide an ability for the customers to change behavior through modifying client settings in the registry.

Conditions

Using APM.

Workaround

None.

Fix Information

The system now uses an F5 Networks-specific captive portal probe URL in BIG-IP Edge Client for Windows instead of the default Microsoft-specific captive portal detection URL. An administrator for a Windows-based system can override use of the F5 captive portal URL by changing the following registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\F5 Networks\RemoteAccess.[ActiveWebProbeHost| ActiveWebProbePath | ActiveWebProbeContent].

Behavior Change
