As far as I understand, it cannot be done with 'balance uri'.

I don't understand what you're trying to express there. You can definitely balance according to any header you like, but I guess you're trying to hack something in there with "balance hdr". I just don't quite understand what it is. Regardless of my miscomprehension, there's probably some way to achieve what you want that others on list can help you with. Probably some hacky combination of "reqrep" and some other req* commands. I must admit I can't visualise the point you're trying to end up at, given that your design *has* to be able to cope with back-end servers going down, hence the balancing strategy can only really be an aid to performance and not an immutable part of the correctness of the solution.
