  • Return Address: This recipe lets you try out Return Address pattern.
  • Correlation Identifier| When sending the request, the sender adds a unique key to request. The receiver processes the request and puts the unique key as the Correlation Identifier in the reply message. Thus when a reply is received independent of the request, the sender knows the request corresponding the received reply based on the Correlation Identifier.
