How to find the ip address of a client machine from a web application?
I need to find the IP address (or the MAC address) of the actual machine that is using my web application. Getting it from the server variables at the server end will not work because the user machines are behind proxies. I need a client-side scripting solution. The users are agreeable to the web application checking for their machine IP and will allow it.
