Sometimes you need to monitor current HTTP sessions for SAP ME - in other words, see how many user are connected and when. Also, you may need to force session end - to free the connection from the idling session.
In Netweaver Administrator, go to Configuration Management -> Infrastructure -> Session Management. Choose necessary Cluster Node and/or Instance. On Session Domain tab you will see open session in Sessions per Domain area. Look for those contexts you need, e.g. /manufacturing. See users logged in and invalidate corresponding sessions, if necessary. The same can be done from the User Context tab.
