Is there any api to retrieve clientIP of the incoming request from Virtualize message stub/responder?
Unfortunately, no. The only way that I know how to retrieve the client IP is to enable monitoring for the Virtual Asset and view the request details under the Event Details Perspective.
Why are you seeking to capture the IP address of the request? What is your use-case? I would appreciate your feedback so that I may pass along the information for a potential feature request.
