>             Project: Qpid Dispatch
>          Issue Type: Improvement
>          Components: Router Node
>    Affects Versions: 0.5
>            Reporter: Ted Ross
>            Priority: Minor
>             Fix For: 0.6
> The message-trace and loop prevention drops messages that have been improperly forwarded
(i.e. forwarded to a router through which the message has already passed).
> This improvement would remove the spurious message transfer by dropping the message before
it is forwarded to a router through which it has already passed.  This requires a change in
the logic around the processing of the trace field.  Instead of looking in the trace for the
current router's ID and dropping the message, the router should use the trace list as an exclusion
list for next-hop forwarding.
