Appending subscriber information to redirect URLs

You can append information about the subscriber retrieved from the subscriber session database when the redirect URL is returned to the HTTP client. You specify the attributes in the redirect URL format in the Activate-Service VSA (26-65) or Deactivate-Service VSA (26-66) included in the RADIUS Access-Accept message when the subscriber is authenticated or in a Change of Authorization (CoA) message. Only the following attributes are supported: subscriber IP or IPv6 address, NAS IP address, requested URL, NAS port ID, MAC address, subscriber session ID, and username.
