title: Differentiate express-session sessions in chrome tabs
body: <p>I am trying to assign to each user a "req.session.pseudo", but when I try to connect in different tabs, it display me the same session.</p>
  
  <p>Here is an exemple with a "req.session.page_views".</p>
  
  <p>Here is the code :</p>
  
  <pre><code>var express = require('express');
  var session = require('express-session');
  var app = express();
  
  app.use(session({
  secret: 'ssshhhhh',
  resave: false,
  saveUninitialized: true
  }));
  
  app.get('/', function(req, res) {
  if(req.session.page_views){
      req.session.page_views++;
      res.send("You visited this page " + req.session.page_views + " times");
  } else {
      req.session.page_views = 1;
      res.send("Welcome to this page for the first time!");
  }
  });
  </code></pre>
  
  <p>the result on my first tab:</p>
  
  <pre><code>Welcome to this page for the first time!
  </code></pre>
  
  <p>the result on my second tab:</p>
  
  <pre><code>You visited this page 2 times
  </code></pre>
  
  <p>I hope to have been clear about my problem. Thank you.</p>
