Issue/Introduction
When virtual service is configured with "Allow duplicate specific transactions" to send round robin response for incoming calls, how will it handle the Connection pool?
Environment
Release : 10.x
Component : CA Service Virtualization
Cause
Sometime, the client application closes connection for each request and the same response is sent from VS instead of round robin responses (multiple specific transactions).
Resolution
The issue is not seen from DevTest 10.5. Even client closes connection for each request, VS will respond in round robin fashion.
Internally, VSE maintains a cache called DUPLICATE_CONTROL_CONTEXT, which holds the last send response index for each VS with "Allow Duplicate Specific Transactions". The response index is incremented such that it cycles through the available number of specific transactions.
Additional Information
Check the documentation on Transactions Tab for Stateless Transactions for more information.
