I am trying to set up a queue to manage traffic to an application on the server that only accepts 250 concurrent users at one time. How would I set up the redirect on the load balancer to redirect the first user that exceeds the 250 concurrent users to a page, for example, that would say "Your request cannot be executed at this time". load balancer - F5 BigIp 2 servers - MS Server 2003 Yes

On VIP definition you can specify the limit of 250 max connections. VIP will not accept any more connections. Thanks.

Thanks for the reply. How do you specify the redirect? Or I should ask, where do you specify the redirect? Also, what is the norm for setting up a redirect page? Would I add a script to keep check the status of the limit within the script and then redirect? Is there a queuing process that I can setup? Yes

I am not sure how to set up redirect. If you want you can use iRules and count the number of connections. if they exceed 250, you can redirect a client to some other site. On 3DNS redirect is via fallback host. Should none of the IPs are available in 3dns, clients are redirected to fallback host. Thanks.
