Rewrite url path using node.js

Question

Is it possible to rewrite the URL path using node.js?(I'm also using Express 3.0)

I've tried something like this:

req.url = 'foo';

But the url continues the same

Sure, just add a middleware function to modify it. For example:

app.use(function(req, res, next) {
  if (req.url.slice(-1) === '/') {
    req.url = req.url.slice(0, -1);
  }
  next();
});

This function removes the trailing slash from all incoming request URLs. Note that in order for this to work, you will need to place it before the call to app.use(app.router).
