Disable Pool Member and Persistence session should die??

This is untested, both in practice and in syntax. but you can give it a try. 🙂

when HTTP_request {

    set pool "MyPool"

    Check if a server has been chosen and if the pool is the right one.
    if { [LB::server addr] and [LB::server pool] -eq $pool } {
        Check the status of the selected member and reject the connection if it's disabled
        if { [LB::status pool $pool member [LB::server addr] [LB::server port]] eq "session_disabled" } {
            reject
        }
    }
}

If you want the rule to also cover when the pool is down you can add an "or" to the "if" statement.
