Express 4.x closes connections after 2 minutes

[admin]

I have a simple node application which handles

GET /foo

. This request takes some time to compute and return a file.
Each time the request lasts more than 2 minutes, the connection is closed. I'm using Express 4.10.2 and node 0.10.32.

I read that http module has a default timeout of 2 minutes: <a href="http://contourline.wordpress.com/2011/03/30/preventing-server-timeout-in-node-js/" rel="nofollow">http://contourline.wordpress.com/2011/03/30/preventing-server-timeout-in-node-js/</a>

I tried to use:

server.on('connection', function(socket) {
    socket.setTimeout(5*60*1000); //5 minutes
});

But even if the connection is not closed after two minutes, when the server tried to send the file back, I got:

{ [Error: Request aborted] code: 'ECONNABORT' }

EDIT:

server.setTimeout(5*60*1000);

works fine! Thanks @mscdex
