Display a "We are overloaded page"
Hi, I would like to display a nice "We are overloaded page" when we are under a high load. In the pool which I am referring to we have a number of "worker" servers and one failover server with a lower priority. So if all "worker" servers are not available (maybe because of failed availability check) then a failover page gets displayed from the failover node. Now I am thinking of putting a "max connection" limit on each "worker" server and if all of them reached that max connection number I want to display a "We are overloaded page" (hosted on another server). Is there a way to distinguish the worker status between "overloaded" and "not available at all"? It would be cool to have something like a function which shows the current amount of connections to a particular "worker" server or all of them in a pool.
Thanks for any ideas...
