Not getting remote address while using proxy in socket.io

Question

In my socket.io code,

socket.sockets.on('connection', function(client){ 
    var ip = client.handshake.address.address;
    ..
}

ip always returns 127.0.0.1 and this is because the server sits behind a proxy. How do I get remote address properly ?

Edit: I am using http-proxy

Checking if client.handshake.headers['x-forwarded-for'] || client.handshake.address.address; will work. — user644745, Jun 25 '12 at 09:44

yes, this is working for me.

client.handshake.headers['x-forwarded-for'] || client.handshake.address.address;

I am properly getting the remote IP address and not 127.0.0.1

Confirmed: This is the first working solution since the last 10 answers I found by google. – Daniel W. May 27 '14 at 13:27
this did not work for me. I am on a networked server/behind proxy, using 1.3.2 – Rachael Jan 20 '15 at 17:08
this one only work for socket 0.9. how about for version >1.0? – John Nguyen Mar 28 '15 at 14:30

In version > 1.0, the syntax is similar:

socket.handshake.headers['x-forwarded-for'] || socket.request.connection.remoteAddress;

For people who may come from Google, using NGINX: none of these worked for me, I followed the answer in this other question and modified my proxy_pass, to create a new header that node could then use. Don't forget to call sudo systemctl restart nginx after.
