[rabbitmq-discuss] Multiple Bindings to the Default Exchange

Mon Jun 24 16:36:09 BST 2013

... if you can't change your publishers, can you change your consumers?
If so, can't you reroute your messages from the default exchange to 
another exchange
and do the processing then against that other exchange?

Cheers
Maze
