title: Set cookie for domain instead of subDomain using NodeJS and ExpressJS
body: <p>I have been using expressjs and mongostore for session management. Following is the code to configure store in expressjs,</p>
  
  <pre><code>app.configure(function(){
      app.use(express.session({
          secret: conf.secret,
          maxAge: new Date(Date.now() + 3600000),
          cookie: { path: '/' },
          store: new MongoStore(conf.db)
      }));
  });
  </code></pre>
  
  <p>I had mentioned the cookie path in the above code. But it sets the cookie in sub.domain.com instead of .domain.com. How do i achieve this?</p>
