One Virtual Server, multiple ports and multiple Pools

Hi,

We need to implement a setup with a group of servers which can have multiple services. Not all services up at the same time in all the servers. They are brought up when needed. We can have 3 services available in a smaller group of servers and another 3 in other group of server. The thing is that we can have 1 server with the 6 services up or we can add or remove some services from the servers at any time.

The simple solution is to create 1 virtual server and 1 pool for each service. The draw back is that we have to replicate the configuration for any service/port that we need to enable.

I was wondering if there is any way to configure some kind of "dynamic pools" where all ports will be part of the pools but the traffic will only be forward to that server if the service/port is available at that moment. We could create only one VS with All ports and configure this pool in the VS.

Probably it can be done with some scripting. Had anyone tryed to configure something like this?

Thanks,

João
