Hi Manoj, 1. It depends how you have everything configured. Haproxy will send requests to a working server if one goes down, it can also retry the failed ones on the working server. If your app has sessions you then need to ensure they are available on the other servers otherwise users will get logged out etc.
2. Yes, just update the haproxy configuration file and reload the service (works perfectly for me on RHEL 6.3 anyway).
