Redirecting user request to maintenance page or another Virtual Server

in case if all of the pool members are down the users should get redirected to the maintenance page, if certain no. of pool members are down users should get redirected to the server busy page.i think active_members could be usable. can you try?

Also if there is a possibility to redirect the user request to another virtual server in case if the no. of requests on a currently working virtual server exceeds by certain value.are these helpful?
