What happens to the attributes of a Mule event after making an outbound HTTP Request?

When a Mule event makes an outbound HTTP request, the attributes of that event are replaced with new attributes reflecting the HTTP response. This means that the original attributes of the event before making the call will no longer exist. Instead, the event will now contain attributes that correspond to the response received from the HTTP request, which may include status code, response headers, and any other relevant information returned by the HTTP service.

This behavior is critical in Mule applications as it allows developers to react to the outcomes of an HTTP call by utilizing the fresh attributes derived from the response, which can be used for further processing or decision-making within the Mule flow.

Understanding this concept helps in effectively managing data flow and ensuring that the correct information is utilized for subsequent operations within a Mule application.
