Hi Is there any support to implement a state-full filters, for example Lets say my code logs a request to a API with a "appId" and server response for the request includes the "appId" sent as part of the request, I need to implement a Filter which would take "appId" as a parameter and enable logging all request/response combination for the specific "appId". One way to implement this is to maintain a thread-safe data-structure and use it to track and compare request appId and the response appId and then log the response for the specific appId. Is there any out of box support for these type of filters ? Regards Vishnu
