4602	Function for getting the clients IP address	hovenko	anonymous	"WordPress misses a function to get the IP address of the original client. It is critical to have a function like this when using plugins for voting, users online and when posting comments when WordPress runs on a server behind an HTTP proxy such as Varnish.

It checks if the header X-Forwarded-For is set (available from {{{$_SERVER['HTTP_X_FORWARDED_FOR'])}}} and uses the first address in this list. If it's not set, it uses {{{$_SERVER['REMOTE_ADDR']}}} instead.

The function also applies a filter called ""remote_ip_address"" before returning the address."	enhancement	closed	normal		General		normal	duplicate	has-patch
