Thanks, was able to figure that that all though logging of the value was intermittent, If I assigned it to another value, say CLIENTIP, I could consistently log that, so now I know it is there. I like this idea too.

We use F5/Apache 2.4/Tomcat , and please note this an Apache that I compile myself. This is what I do to resolve this problem : -download mod_rapf-0.6 -download rpaf patch ( http://www.be-root.com/downloads/mod_rpaf/mod_rpaf-2.0.patch ) and apply it ( patch -p0 < mod_rpaf-2.0.patch) -compile mod_rpaf ( example : /usr/local/httpd-2.4.12/bin/apxs -i -c -n mod_rpaf-2.0.so mod_rpaf-2.0.c ) -load and configure the module in httpd.conf : LoadModule rpaf_module modules/mod_rpaf.so <IfModule rpaf_module> RPAFenable On RPAFproxy_ips 127.0.0.1 (and others ip if needed) RPAFsethostname On </IfModule> -at the tomcat level I need to configure a special logging valve <Valve className="org.apache.catalina.valves.RemoteIpValve" /> 2016-03-20 14:15 GMT+01:00 Abernathy, Don <DAbernathy@xxxxxxx>: We are running Apache behind an F5 fronting JAVA Container (WebSphere) and the JAVA code makes an HttpServletRequest.getRemoteAddr() request to get IP. The IP I am told is the one that the CGI REMOTE_ADDR server parameter of Apache provides, but when I try to log that value to see what it is, I get null. I am under the impression that there is no setting to turn on, but that it should work. I will note that the Apache I am running is the IBM Version, known as IBM Http Server. I have asked the my team to look at using X-Forwarded-User, but how would I set it up so that the query for IP returns that, or do we ask the JAVA Developer to change the Code to support checking for X-Forwarded-User, NOT getRemoteAddr?
