Hello Yodying,
Further to our call few minutes ago, I was working on this case today and had some doubts on this.
This was the configuration passed on to me by previous engineer:
********************
add cr policy bypass-all -rule ns_true
add cr policy TEST_BYPASS_149 -rule "REQ.IP.SOURCEIP == 202.44.238.149"
add cr vserver vip_cr HTTP * 80 -cltTimeout 180 -reuse OFF -l2Conn ON -originUSIP ON
bind cr vserver vip_cr -policyName bypass-non-get
bind cr vserver vip_cr -lbvserver vip_forward
add service service_forward server_forward HTTP 8888 -gslb NONE -cacheType TRANSPARENT -maxClient 0 -maxReq 0 -cip DISABLED -usip YES -useproxyport NO -sp OFF -cltTimeout 180 -svrTimeout 60 -CKA NO -TCPB NO -CMP NO
bind lb vserver vip_forward service_forward
ACL bridge disabled:
add ns acl test-summoner_war BRIDGE -srcIP = 203.150.118.138 -priority 10 -state DISABLED -kernelstate SFNOTAPPLIED61
**********************
There are 2 CR user defined policies and one pre-defined policy here. Though it is the bypass-non-get is what is bound to the CR vserver I would like clarification that this is how it was tested.
Please note that the default behavior of the NS is that whenever a traffic matches a CR policy that traffic is sent to the Origin server. Only those traffic that does NOT match the CR policy is sent to the Cache server.
So As per above policies – when traffic hits policy “bypass-all” or coming from source ip 202.44.238.149 or if it is a non-GET http request they are sent to the Origin server respectively (depending on what policy is bound to CR vserver).
So I hope your understand was correct when you added these configuration.
I do not have information to analyze the trace as this is a transparent CR configuration in the front end and no client ip address has been mentioned (I tried to filter using source ip 203.150.118.138 but nothing came of it).
To check backend connection to Cache server I tried to filter using Cache server’s ip address 1.1.1.1 (which does not seem to be real though in all 3 uploaded configs this is the ip address for service associated with lb vserver vip_forward) I could not find any connection for this as well.
add lb vserver vip_forward HTTP 0.0.0.0 0 -persistenceType NONE -lbMethod URLHASH -m MAC -cacheable YES -cltTimeout 180 -l2Conn ON
bind lb vserver vip_forward service_forwardadd service service_forward server_forward HTTP 8888 -gslb NONE -cacheType TRANSPARENT -maxClient 0 -maxReq 0 -cip DISABLED -usip YES -useproxyport NO -sp OFF -cltTimeout 180 -svrTimeout 60 -CKA NO -TCPB NO -CMP NO
bind lb vserver vip_forward service_forward
add server server_forward 1.1.1.1
Could you give me a brief description of the issue first as I am not really clear form the case notes?
If you have a topology diagram could you provide that as well?
Is hub.com2us.com 112.175.60.20 the Origin server?
Also, as I understand these traces were taken quite a while back and I can understand you may not have information on this now to help me with analyzing the trace. Can we troubleshoot this over a GTM (and taker new traces if needed) , after we have a clear understanding of the objective and configuration?
