FSM - Expire users session in WebClient after a deployment is made

Hi IFS community, 

have a client where there is a request to automatically force the users to relogin after there is a deployment done.

I know there are 2 app parameters that related to this : CLIENT_TIMEOUT and SESSION_TIMEOUT but these parameters are not automatically forcing the users to timeout in the WebClient version.

The IFS Release on FSM is Release: 6 Update 29Release: 6 Update 29.

Have also found a perform message that works in FSM Smart Client version but not in WebClient:

<perform_logout_person>

  <parameters>

    <person_id> @person_id </person_id>

  </parameters>

</perform_logout_person>

So, does anyone know of a way to force a user to logout or relogin after we perform a deployment on an environment?

Thanks!
