Circuit ID as a Public Spot URL-redirect variable

As of LCOS version 9.20, the redirect variable "%d" enables you to display different welcome pages on authenticated clients, depending on their location.

%d

Enter the URL parameter '%d' as the circuit ID, for example http://ipaddress/?circuit=%d&nas=%i. The Public Spot module replaces this variable with the circuit ID that is detected in the client's DHCP request. This requires "DHCP snooping" to be configured on the AP in such a way that the AP can query the circuit ID in the Public Spot station table of the WLC. In this way it is possible for the Public Spot welcome page displayed on the clients to be customized by location.
