as I understand you right you want to do something like this.
pseudo code:
for host in iis1 iis2 ... iisN do
check GET /Login/Heartbeat HTTP/1.1\r\nHost:\ $host
I don't know if this is possible with lua, with 'normal' haproxy I don't
think so that this is possible.
But should the vhost not be the same on all servers?
