Passing IP address with mod_proxy

Question

I have Apache with mod_proxy passing requests to Tomcat. The trouble is, when I get client IP address associated with a request in web app hosted on Tomcat, it always returns 127.0.0.1.

Is it possible to have Apache pass the original IP address to Tomcat?

Answer 1

The X-Forwarded-For environment variable should also be set by default with mod_proxy

Answer 2

I'd recommend using mod_jk or mod_proxy_ajp if you're wanting to retain information about the original requests source ip address.

Answer 3

Your configuration should include ProxyPreserveHost On, similar to

<VirtualHost *:80>
  ServerName public.server.name

  ProxyRequests Off
  ProxyPreserveHost On

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:8180/
  ProxyPassReverse / http://localhost:8180/
</VirtualHost>
