Re[rules-users] ading incoming connection in Action - Rule flow

[Thalupula Ravi]

Hi Kris,

Thanks for your information.

Actually i have an action, which is common to a couple of splits, so in my
action i need to log(log4j - file appender) that from which split request is
coming from.

I mean to say, on based on incoming split request, different message need to
be log.
