Problem Description

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.
