Hi,

I just started testing reverse proxying to from apache 2.4 to a backend wildfly 8.1 server using mod_proxy_ajp on centos 7, using this config:

(from conf.d/vhosts.conf):

<VirtualHost ...>
...
ProxyRequests Off

<Proxy balancer://cluster>
BalancerMember ajp://127.0.0.1:8009
</Proxy>
ProxyPass / balancer://cluster stickysession=JSESSIONID

ProxyPassReverse / balancer://cluster
...
</VirtualHost>

(from conf.module.d/00-proxy.conf):

# This file configures all the proxy modules:
LoadModule proxy_module modules/mod_proxy.so

LoadModule lbmethod_bybusyness_module modules/mod_lbmethod_bybusyness.so
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so
LoadModule lbmethod_bytraffic_module modules/mod_lbmethod_bytraffic.so

LoadModule lbmethod_heartbeat_module modules/mod_lbmethod_heartbeat.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_express_module modules/mod_proxy_express.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
LoadModule proxy_fdpass_module modules/mod_proxy_fdpass.so

LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_scgi_module modules/mod_proxy_scgi.so

When I request the / URL, the main document loads successfully, but the CSS and image resources fail to load with 500 internal server errors. From the apache ssl_error_logs:

From what I can find from searching around, this is mostly due to people not loading the correct proxy submodule, however the 00-proxy.conf config is loading every proxy submodule there is.

is there anything anyone can see that I'm doing wrong?

thanks
