[users@httpd] How to add HTTP_X_FORWARDED_FOR header

[Stephen(Tie) Hu]

Hi, 
    I am using apache http server as a proxy. It's working quite well except it 
doesn't add HTTP_X_FORWARDED_FOR header. Does any one know how to force apache 
to add HTTP_X_FORWARDED_FOR header? 1000 thanks in ahead!

    Here is my apache server's version: 
Server version: Apache/2.2.6 (Unix)
Server built:   Sep 18 2007 11:26:13


    Here is my apache configuration section: 
ProxyRequests On
<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>

KeepAlive On
MaxKeepAliveRequests 100
AddDefaultCharset Off


Very Best Regards!
Stephen
