title: proxy request in node.js / express
body: <p>I have a nginx server as a front end to a node.js application.<br>
  When the request gets to the application, I'd like to slightly modify it (the request) and forward it to another node.js application. What would be the best way to do this ?</p>
  
  <p>I was thinking of node-proxy but as I use expressjs in the node apps, I'm not really sure how to use node-proxy and express at the same time.  </p>
  
  <p>any idea ?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>Could I use res.redirect in my expressjs routes to forward to other node.js application ? I have just tried this but it does not work as expected. </p>
