Maybe I haven't described this properly. We want all sites no matter the top level domain to come into the same VIP. That VIP uses an iRule for the host header to send the connection to the proper pool. I need a generic iRule that will look at the host header and if the pool that corresponds to that host header is down I would like to send the iFile app offline.

 

Example (abc.123.com, 111.ZZZ.com & 222.BBB.com) all have the same public IP and come into the same F5 VIP, however the VIP uses an iRule for host headers to send the connection to the correct pool. When that pool just happens to be down I would like an iRule to send an app offline page.
