Thanks Timo, I just tried out the Director. One question is about the re-redirection. I know director will redirect all the simultaneous requests from the same user to only a single server at the same time. The question is how to manage the time period after last connection to re-decide to redirect which machine? director_user_expire? Look like not.
I did one test, set director_user_expire = 1 min, then keep sending
requests to the director in 2 min interval, the result is it keeps redirect
to the same back end server.
Actually what i want is the "secondary load balancer layer" can redirect
requests to random back end. How to manage it? Only after the files on the
previous back end is expired?
Thanks.

I don't even attempt to support this kind of configuration anymore. Use
