Okie. This is what I see from how its happening:

1. There is a login page
2. When login page is loaded I see an entry for a session put in.

+-----+----------------------------------+-----------------------------------------------------------------------------------------------------------------------------------------+---------------------+---------------------+
| id  | session_id                       | data 
| created_at          | updated_at          |

3. When someone logs in successfully, I set the user_id value in the 
session variable. Right then I see that the sql record has the value in 
"data" variable changed.

      session[:user_id] = params[:email]

4. When someone logs out, I clear the value and call reset_session. 
Again I see the sql record has the "data" variable with changed value.

    session[:user_id] = nil
    reset_session

Hence the problem is:
1. Can't I ensure a session record is created only when I want - After 
the user logs in ?
2. If not, Can I differentiate a authenticated session vs 
unauthenticated sessions (sessions where the login page was just loaded 
OR sessions where the user logged out) ?
