+<P>From Apache ActiveMQ <B>4.2</B> onwards you can now use selectors to define virtual destinations.</P>

+<P>You may wish to create a virtual destination which forwards messages to multiple destinations but applying a selector first to decide if the message really does have to go to a particular destination.</P>

-<P>Yes. You have to make sure that the messages sent to the 'Consumer.*.VirtualTopic.>' destination are not forwarded. This can be done by configuring the network connector something like:</P>

-<P>If you use Virtual Topics in a network of brokers, it is likely you will get duplicate messages if you use the default network configuration. This is because a network node will not only forward message sent to the virtual topic, but also the associated physical queues. To fix this, you should disable forwarding messages on the associated physical queues. </P>
