How to get Client IP address

[codeexploiter]

In PHP use the following line. The client ip will be in $ip variable


$ip = $_SERVER['REMOTE_ADDR'];

in ASP.NET use the following in the following order - first check the first option if it returns empty then use the second one


Request.ServerVariables("HTTP_X_FORWARDED_FOR");
Request.ServerVariables("REMOTE_ADDR");

Checking for $_SERVER['HTTP_X_FORWARDED_FOR'] would be good practice in PHP too.
