welcome-back
  
  
    
      Enables the provision of direct Internet access to once-registered,
        captive-portal guest users on subsequent log-ins. When enabled, a registered captive-portal
        guest user, on subsequent logins, is served the Acknowledgement page only if:
      
        - The agreement-refresh option is enabled for device-based (device and device-OTP)
          registration, and
- The interval between logout and login is lesser than the agreement-refresh timeout
          configured in the WLAN context. If this interval exceeds the agreement-refresh timeout,
          the user is served the Agreement page. For more information on configuring the
          agreement-refresh timeout value, see registration.
