Hi, When i try to get http://www.dnsstuff.com/. i got above output on that site page. And when i enable forwarded_for option in squid.conf i can get my customer ip ( local / private ip) at that site.But instead of that i want my squid server public ip. Kindly guide me for that. I want to derive more punch to understand http header request and reply via squid and want to debug http header in good manner.So please guide me for that , is there any plugin / add on or any open source utility , from which i can see what header options are passing to remote server when i try to surf sites.because in some sites which shows ip and other information related it , from those sites i got my squid version and squid information. Currently I m runnig squid on my lan ip. Squid version: 3.1.8 OS : centos 5.5 Regards, Benajmin
