We're building a webfarm, using F5 load balancer big-ip, and 2 MS Server 2003 boxes. If the network will handle only, let's say, 250 concurrent users, how would I go about setting up a queue for the 251st person and up. I would like to have the 251st user and up go to a "Please wait.." page until traffic clears up. How would I go about setting this up? How do you think, for example, ticketmaster handles this?
