Nice little tool! Quick question though: does this script actually block HAproxy's event loop while waiting for the response from the backend server? (I've read quickly through your article describing the script, but failed to get a clear answer to this question. Moreover looking at the script, unless HAProxy does something "funky" with the Lua interpreter to give the impression of a synchronous API, I would say it does block the HAProxy thread that calls this script.) Thanks, Ciprian.
