如何在Node.js服务器中设置HTTP Keep-Alive超时

对于Express 3：

var express = require('express');var app = express();var server = app.listen(5001);server.on('connection', function(socket) {  console.log("A new connection was made by a client.");  socket.setTimeout(30 * 1000);   // 30 second timeout. Change this as you see fit.});
