I have 5 VIP.s pointing to the same 2 real servers. I use HTTP/1.1 to differentiate the sites on the webservers. When one of the sites is down for maintenance the healthcheck takes the entire real server down even for the other 4 sites. It goes back up again as soon as it checks the health on another site. Then down again when it comes to the site under maintenance and so it continues until all sites are back up again. I have disabled drainstop on real servers on failure so the sites misbehaves to say the least.
On the start page it says I have 10 real servers but when I click details it only shows the 2.
Can I use SubVS so that only the current site is affected by maintenance or how can I configure this without setting a different IP for each site on each RS?
