The CA Data Protection iConsole uses the IIS "System.Web.SessionState" class to maintain the HttpSessionState. The configurable timeout value is assigned to the current session state.
To lengthen or shorten the automatic session timeout, or to adjust how long the session timeout warning is displayed, you need to modify values in the Web registry key on the front-end Web server.
Within this registry key, modify the following values:
Data: Defaults to 20. Specifies how long (in seconds) the session timeout warning is displayed before the user is redirected to the Reconnect screen.
Data: Defaults to 20. Specifies the session timeout (in minutes) for the iConsole. The timeout countdown begins as soon as the user logs on to a CMS and restarts each time CA Data Protection detects user activity. If the timeout expires and no user activity was detected, CA Data Protection terminates the current session and displays the iConsole Logon screen.
