Regarding dropping of slow consumer

Hi

I read about slow consumer from this URL:
http://activemq.apache.org/slow-consumers.html
Non-Durable Topics

Non-durable topics are the scenario which is most affected by slow consumers
since the messages are not persistent and messages generally go to all
consumers (who have a valid selector)

Here are the various things we can do

    * block/slow the producer
    * drop the slow consumer
    * spool messages to disk
    * discard messages for the slow consumer

These will be exposed as a pluggable policy for the user. 

Is there any configuration to be done in activemq.xml for dropping slow
consumer or discard messages for slow consumer? Or should this be handled in
any other way?

Thanks
Badri
