Run OHS for Weblogic cluster - weblogic

Question

I am using weblogic12.1.3
I was install the WebLogic cluster in the above format :
cluster name : cs1, cluster address 172.30.35.23:7003,172.30.35.23:7004
I have 2 manageserver : 172.30.35.23:7003,172.30.35.23:7004
and a Machine MCH1(added 2 manage server to this machine)
my console address is : 172.30.35.23:7001/console
I have installe OHS on the other server : IP:172.30.35.13 port:7777
===============================================================
My configuration in OHS (mod_wl_ohs.conf) is :
LoadModule weblogic_module /u01/app/product/fmw/ohs/mosules/mod_wl_ohs.so
<IfModule weblogic_module>
<Location /console>
WLSRequest On
WebLogicHost 172.30.35.23
WeblogicPort 7001
</Location>
</IfModule>
<IfModule weblogic_module>
<Location /Hello>
WLSRequest On
WebLogicCluster 172.30.35.23:7003,172.30.35.23:7004
</Location>
</IfModule>
=============================================================
my /etc/hosts on weblogic server is :
127:0.0.1 localhost.localdomain
172.30.35.23 weblogic2 weblogic2.localdomain
my /etc/hosts on OHS server is :
127:0.0.1 localhost.localdomain
172.30.35.13 OHS OHS.localdomain
==============================================================
I deployed Hello.war to cluster
My test result :
172.30.35.23:70001/console is ok
172.30.35.13:7777/console is ok
172.30.35.23:7003/Hello is ok
172.30.35.23:7004/Hello is ok
but i dont have any answer on 172.30.35.13:7777/Hello
why ?
It means OHS is not working with cluster ?
ohs1.log is :
[oracle#OHS logs]$ cat ohs1.log

You need to make WebLogic Server to accept OHS request
If the version of the Oracle WebLogic Server instances in the back end is 10.3.4 (or later releases), you must set the WebLogic Plug-In Enabled parameter.
1.
Log in to the Oracle WebLogic Server administration console.
The WebLogic Proxy Plug-In provides features that are
identical to those of the plug-in for Apache HTTP Server.
2.
In the Domain Structure pane, expand the
Environment node.
– If the server instances to which you want to proxy requests from Oracle
HTTP Server are in a cluster, select Clusters.
– Otherwise, select Servers.
3.
Select the server or cluster to which you want to proxy requests from Oracle
HTTP Server.
The Configuration: General tab is displayed.
4.
Scroll down to the Advanced section, expand it, and select the
WebLogic Plug-In Enabled checkbox. Or change value from default to yes if there isn't checkbox
5.
Click Save.
6.
If you selected Servers in step 2, repeat steps 3 and 4 for the other servers to which you want to proxy requests from Oracle HTTP Servers.
For the change to take effect, you must restart the server instances.
