Abstract
Techniques to allow applications to propagate information to the other instances of the applications running on downstream servers are provided. An indicator, such as a token, tag, etc., is placed within or added to a message that is flowing through the distributed environment to signify that a process has been performed on the message. For example, when an instance of an application running on a server receives a message, the application instance can examine the indicator contained in the message and take appropriate action. If the application instance decides to process the message, the application instance can include an indicator in the message to signify that the application instance processed the message. The presence of the indicator signifies that the message has been processed by an upstream instance of the same application.
