Why do I need this? The right answer is: I don’t need that trick!

The example below is just to show how to use routes to intercept requests to a static file.

Put router before static.

app.use(app.router);
app.use(express.static(__dirname + ‘/static‘));

Add ‘/*’ handler (don’t forget to call next())

app.get(‘/*‘, function(req, res, next){ 
  res.setHeader(‘Last-Modified‘, (new Date()).toUTCString());
  next(); 
});

method 2()

app.use(function(req, res, next){
  res.header("Cache-Control", "no-cache, no-store, must-revalidate");
  res.header("Pragma", "no-cache");
  res.header("Expires", 0);
  next();
});

method 3

Easiest solution:

app.disable(‘etag‘);
