Thanks Jonathan for clarifying the problem further for me. So, how I would go about what I want is to:
1. Apply the necessary changes to haproxy.cfg such that in the next restart/reload they would be picked up and in a consistent state 2. Use socat to apply the same changes at runtime for them to take effect Now, for me the question becomes about the runtime part that: 1. Using socat completely allow me to add, remove, enable, and disable endpoints and rules in runtime? 2. Is there another way but socat to achieve this at runtime?

Here is my situation, I have a script that modifies haproxy.cfg; e.g. it may add new endpoints, remove them, enable or disable them. I want to verify on which of the situations above, it is required that HAProxy process is reloaded/restarted so that the configuration takes effect? To answer your exact question: absolutely no changes to the config file on disk will be picked up by the HAProxy process(es) without you first restarting/reloading the process. NB Do note that that doesn't answer the wider question about making changes to a running process' *idea* of what its configuration should be. That can be done in a variety of ways, but not via the config file itself. I'm not best placed to help you with that, however.
