update: not very smart with http_get as haproxy is configured to RR between apache. Thus if 1 apache is down, it will still reflect as real server down, which is not how i want it, i only want it to be down only when all apache of the webfarm is down.
the vrrp_script is checking if haproxy is running in process which is good if haproxy crashes, however would be similar to TCP_CHECK on haproxy(transparent proxy).
