Hi,
I will agree to what Kenneth said. "never assume"
I did assume is config issue on the appserver side at the first time,
but it turns out is the system setup issue (networking issue - loopback
is not setup correctly).
Never assume all system work/config the same way. A lesson well learn.
Thanks,
Homer
