http.client.persistence(preserve) policy does not apply under certain conditions
The “http.client.persistence(preserve)” policy, which is used to prevent TCP port re-use, does not apply when the following conditions are true: - Reflect Client IP is configured - Object caching is enabled - Transparent deployment
When the server is not the one that closes the connection, the ProxySG does not implement the client persistence policy. As a result, the client connection stays open, and this causes the ProxySG to re-use the connection it has just closed with the server.
