BTW: I wrote notes while getting multicast working and blogged about it: <a href="http://bradfordcross.blogspot.com/2009/05/multicast-rabbitmq-from-clojure.html">http://bradfordcross.blogspot.com/2009/05/multicast-rabbitmq-from-clojure.html</a><br>

My requirement is to have two parallel (forked, or whatever) queues, one of which the regular production process listens to, and one of which a backup process listens to.<br>
<br></div>
Rabbitmq seems to call this sort of thing one-to-many broadcasting and multicast. There is not a lot of documentation about it, just a blurb here <<a href="http://www.rabbitmq.com/faq.html#scenarios" target="_blank">http://www.rabbitmq.com/faq.html#scenarios</a>> and then the code here -> rabbitmq-java-client-1.5.4/test/src/com/rabbitmq/examples/MulticastMain.java<br>

Briefly, to get a message sent to multiple queues, bind those queues to an exchange using binding keys that match the message's routing key.<br>
<br>
Btw, MulticastMain is a fairly universal test program, so it's not exactly a concise example of performing simple multicast routing.<br>
