Apache - httpd.conf redirect with X-Forward-For - Not working?

  • 772

I'm having an a-hole of a problem redirecting traffic. Basically, I'm building a new web server and it's on another version of my domain, so I want to redirect traffic not from this IP.

Problem is Amazon's ELB Load Balancer is in the way, so it replaces REMOTE ip address. The normal method of obtaining. Research found I need to use %{X-Forward-For}i - but it's not working and I don't know if I've got it in the right placement and syntax. I'm running vhosts, so I put in the VirtualHost tags...

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/vhosts/foo/www.bar.com/htdocs/
    ServerName www.bar.com
    ErrorLog /var/www/vhosts/foo/www.bar.com/logs/error.log
    CustomLog /var/www/vhosts/foo/www.bar.com/logs/access.log common
    RewriteEngine On
    RewriteCond %{X-Forwarded-For}i !^xxx\.xxx\.xxx\.xxx
    RewriteRule ^.*$ http://www.bar.com/ [R,L]
</VirtualHost>

Obv xxx.xxx.xxx.xxx being my IP.

Is this wrong?

apache-2.2 redirect httpd mod-rewrite 301-redirect

    On the top of my head: shouldn't this 

    RewriteCond %{X-Forwarded-For} !^xxx\.xxx\.xxx\.xxx

    be

    RewriteCond %{HTTP:X-Forwarded-For} !^xxx\.xxx\.xxx\.xxx

    or just

    RewriteCond %{HTTP_FORWARDED} !^xxx\.xxx\.xxx\.xxx
