>            Assignee: Tim Armstrong

> Currently, the Debug WebUI's Sessions page captures both active sessions and expired sessions. On the top of the page there is a message along the line of:
> {noformat}
> There are {{num_sessions}} sessions, of which {{num_active}} are active. 
> Sessions may be closed either when they are idle for some time (see Idle Timeout
> below), or if they are deliberately closed, otherwise they are called active.
> {noformat}
> This text is ambiguous for me. If all non-active sessions are expired sessions, it should explicitly tell the user that. And since an active session becomes an expired session when it breaches the Session Idle Timeout, the second sentence is also somewhat misleading. User has to "deliberately close" both active sessions and expired sessions to close them.
