Resolution:
Yes, we can do that.

Flow control can be specified on destinations that are bridged to other destinations. If you wish the flow of messages sent by way
of the bridge to slow down when receivers on the bridged-to destination cannot process the messages quickly enough, you must set
the flowControl property on both destinations on either side of the bridge.

The flowControl will take effect only when the source destination is set flowControl (of course, flowcontrol should be enabled from
EMS main configuration file).  If the source destination is not flowControl, only target destinations are set flowControl, the flowControl
will not take place.
