note 38157 added to language.variables.predefined

In reply to the comment posted on 01-May-2003 03:06 Be carefull when using the $_SERVER["HTTP_X_FORWARDED_FOR"] variable for determining the visitors IP address. I sometimes note that the variable contains the string 'unknown' and is therefore not empty. So checking with isset() won't always guarantee that it contains a usable IP address. It also sometimes contains two IP addresses, separated by comma.
