I have an existing iRule that directs traffic to various pools based on the host name. It was requested that connections from specific source IPs be directed to specific nodes. I added this functional...

Try this: 



when CLIENT_ACCEPTED {
  set httpfunctions 1
  if { [IP::client_addr] equals 1.2.3.4 } {
    node 192.168.10.10 80
    unset httpfunctions
  }
}

when HTTP_REQUEST {
  if { [info exists httpfunctions]} {
    if { [HTTP::host] contains domain1.com {
      pool domain1.com_pool
    }
    elseif { [HTTP::host] contains domain2.com {
      pool domain2.com_pool
    }
    else {
      pool domain.com_pool
    }
  }
}

Basically you want to do an event disable, but only for the context of this iRule, not all the HTTP_REQUEST events in all the iRules. So this should get you there.
