scenario: users use a client/browser which is located on the company lan using a private IP address the company lan is protected by a firewall which translates all web access into one public IP address the proxy is implemented as a 'cloud service' which does only see the translated (nat'ed) public ip for all clients/browsers in this company i am curious if there exists a solution which works for IE, firefox, opera, ... had a look at: - X-Client-IP header - Flash Local Stored Objects - HTTP Cookies but neither seems to match for my scenario ;( any ideas or has anyone implemented such a solution yet? thank you /pat
