Foundry Networks makes a load-balancer box that is able to keep itself synced with another unit for both fail-over and load-balancing. The unit balances requests to whatever backend servers you have, and if one of the backend servers croaks, the Foundry unit stops sending requests to it. This solution give you complete backend and frontend redunancy. Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
