wsclient-endpointAddress on a clustered MWS environment

Hi,

Do you know if the wsclient-endpointAddress property on CAF Application Runtime Configuration is shared between nodes on a MWS clustered environment? If I change the portlet application to point to IS on hostA, will it apply the same configuration on the other MWS node?
From my experience I would say it seems to share, but not immediately. Does it require a restart on the application or the MWS node?

thx
Bruno
