Hi Kit,
Thank you for your quick reply! It is the second, I run "for i in `seq 1
2000`; do curl 3.94.168.82:8080; done”, then only a few responses are back.
(the ip is valid, you can try too).
I checked the var/log/ directory and I don’t see any problem shown in the
log except almost everything is miss.
I am using an unmodified ATS v8.0.2, so I suspect it is my setting problem,
I am testing it on AWS and I have attached my configs below. (I know the value
are weird, this is for testing)
Thank you!
