Hi Krishna, I found a bug explaining your observations and noticed a second one I have not yet troubleshooted.
The bug causing your issue is that before moving the idle connection back to the server's pool, we check the backend's http-reuse mode. But we're doing this after calling http_reset_txn() which prepares the transaction to accept a new request and sets the backend to the frontend. So we're in fact checking the frontend's option. That's why it doesn't work in your case. That's a stupid bug that I managed to fix. While testing this I discovered another issue (problably less easy to fix, I'll see). If the client closes an idle connection while there are still other connections left, the server connection is not moved back to the server's idle list and is closed. It's not dramatic, but is a waste of resources since we could maintain that connection open. I'll see if we can do something simple regarding this case. I'll send a patch soon for the first case. Thanks, Willy
