iRule to disable a node when health check fail

iaine, I am using only a customized HTTPS health check, but once the user get logged in, then other processes start and keep the session up. The login page and JVM are on the same server and are seen as a single big process (only one health check). Basically the user log in and then there is a specific interface (Java + some Oracle connectors) doing the job. That UI remain up and running even if the login page fail. That's why I was looking for disabling the node instead marking it down.
