I am using the apache http server to proxy the request from brower and load balancer, the version is 2.4.23, also I am working with module named mod_proxy_hcheck to check the worker healthy, but I am failed, I have do a lot of work to check the configuration and solution, but it is not use, so can you help me to find the problem, Because this function is the lastest,
also I can not find the answer from internet.
This is the core configuration below(you can also find this in the attachment):
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot "/usr/local/apache/htdocs"
ServerName localhost
ServerAlias localhost
ProxyPass /examples/servlets/ balancer://cluster/examples/servlets/
ProxyPassReverse /examples/servlets/ balancer://cluster/examples/servlets/
ErrorLog "logs/dummy-host2.example.com-error_log"
CustomLog "logs/dummy-host2.example.com-access_log" common
</VirtualHost>
ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyHCExpr ok23 {%{REQUEST_STATUS} =~ /^[5]/}
#ProxyHCExpr in_maint {hc('body') !~ /Under maintenance/}
ProxyRequests Off
<proxy balancer://Testcluster>
BalancerMember http://localhost:8181/examples/servlets loadfactor=1 hcmethod=GET hcexpr=ok234 hcinterval=15 hcuri=/status.php
BalancerMember http://localhost:8282/examples/servlets loadfactor=1 hcmethod=GET hcexpr=ok23 hcinterval=15 hcuri=/check
ProxySet lbmethod=byrequests
</proxy>
#ProxyPass "/" "balancer://cluster"
#ProxyPassReverse "/" "balancer://cluster"
<Location /balancer-manager>
SetHandler balancer-manager
Order Deny,Allow
Deny from all
Allow from all
</Location>
But I find the log in tomcat, the result is :
127.0.0.1 - - [29/Jul/2016:23:07:40 +0800] "GET /examples/servlets HTTP/1.0" 302 -

127.0.0.1 - - [29/Jul/2016:23:09:00 +0800] "GET /examples/servlets HTTP/1.0" 302 -
It looks like the parameter "hcuri=/status.php" or "/check" does not affect.
Can you help me to find the problems? I can not find the answer from document in the official website.
Thank you very much!
Best Regards.
