    The cookie domain for SMSESSION defaults to the (host -1) domain


    So where it used to be
       set-cookie SMSESSION =*** 

    it is now: 

        set-cookie SMSESSION =*** 


    and so SMSESSION is then not sent to requests to the host since it is not in the domain.



    A fiddler trace, or the console trace in browser to view the set-cookie is good way to confirm.


    There are a number of ACO parametrers you can set. : 




    in the agent to influence it, probably would be the easiest - but depends on your setup.


    Cheers - Mark
