8.3.13. Routing Key Wildcard Examples
The following table demonstrates the interaction between routing key wildcards in ACL rules and message headers. Along the top of the table are routing keys with wildcards. Down the left-hand side are message headers.
The character
X indicates that the message with the given header will not be routed given an ACL rule that allows messages with the specified routing key. 'Routed' indicates that the message with the given header will be routed by an ACL rule that allows message with the specified routing key.
