ultramonkey failover between realservers rather than load balancing?

[Jon Neher <jneher@xxxxxxxxxxxxxxxxxxxx>]

We've been using ultramonkey/heartbeat for a while with one
director (with a failover director) to load balance some services
to 2 realservers and it's working great.  We have a situation
now where we need to only have one realserver (r1) being routed to
at a time and then have the other realserver (r2) routed to only
in the case that the services become unavailable on r1.

Does anyone have any suggestions on how best to configure this?

Thanks,

Jon
