Hi, As we discussed below, for only webservice calls X-Forwarded-For header is not added from apache, remaining other technologies it is adding fine. One more thing is, X-Forwarded-Host is working always - even for webservice call as well. I reported bug on this https://bz.apache.org/bugzilla/show_bug.cgi?id=61750 now.
