Description

Every time a new connector is created dynamically, the router will create a new connection for any existing connector. E.g. with some amqp server listening on ports 5673 and 5674:

$ echo '{"host":"localhost","port":5673}' | qdmanage CREATE --type=connector --name=foo --stdin
{
  "verifyHostname": true, 
  "stripAnnotations": "both", 
  "name": "foo", 
  "idleTimeoutSeconds": 16, 
  "allowRedirect": true, 
  "messageLoggingComponents": "none", 
  "maxFrameSize": 16384, 
  "host": "localhost", 
  "cost": 1, 
  "role": "normal", 
  "failoverUrls": "amqp://localhost:5673", 
  "maxSessions": 32768, 
  "type": "org.apache.qpid.dispatch.connector", 
  "port": "5673", 
  "identity": "connector/localhost:5673:foo"
}
