I have two webservers:

  • WEB A: 192.168.0.3
  • WEB B: 192.168.0.4

and am using haproxy to load balance between them.

How do I configure haproxy to detect when WEB A or WEB B dies and stop forwarding connections there?

You want to ask haproxy to use HTTP status checks to detect failed servers.

Search the configuration guide for http-check and httpchk.

You'll end up with something like:

backend brazzers
        mode http
        balance roundrobin
        option httpchk GET /status HTTP/1.1\r\nHost:\ api.brazzers.com
        server  bz_00 10.0.0.1:8000 check
        server  bz_01 10.0.0.2:8000 check
