I am injecting a header with a rewrite policy on my LB to pass X-Forwarded-For 
header. Have verified that this appears on all the pages in the RESPONSE Header.

I have the following config in server.xml , yet i am not able to see the Remote 
IP/X-Forwarded-For either using %a or %h (I see Loadbalancer IP)

What could be the issue?

            <Valve className="org.apache.catalina.valves.RemoteIpValve"
              internalProxies="10\.202\.13\.198"
              remoteIpHeader="X-Forwarded-For"
              proxiesHeader="x-forwarded-by"
              requestAttributesEnabled="true"
            />
            <Valve className="org.apache.catalina.valves.AccessLogValve"
              directory="logs"
              prefix="localhost_access_log"
              suffix=".txt"
              pattern="%t %a %h %{Referer}i %l %S %{User-Agent}i %U %s %r %q %A 
%v %p %b %I %D"
              requestAttributeEnabled="true"
              resolveHosts="false"/>

As you see : both %a and % h are : 10.202.13.198 10.202.13.198 (my LB IP)
