RE: Geographically separated load balancers?

["Neil Aggarwal" <neil@xxxxxxxxxxxxxxxxxx>]

Joe:

I am thinking there will be two physical machines.
Each machine will run a director and a real server.

Are there any docs on how to set up the VIP and
routing for this scenario?

Thanks,
        Neil

do you want two realservers, each in a different place, or 
two directors each in a different place?

you'll have to arrange for the two different locations to 
accept packets for the VIP (or packets to the URL).

yes. you just have to set up the routing.
