Serving static content on dynamic url with expressjs

maybebetter.js

//Create a module for static middleware instanciation with a singleton
//Use the same singleton for app.use and variable routing.
//If there is some caching stuff going on, they should share the same cache which is a lot better.
var express = require("express");
var static = null;

module.exports = function(){
  if(!static){
    static = express.static(__dirname+"/public");
  }
  return static;
}

route.js

module.exports = function(req,res,next){
  var static = express.static(__dirname+"/public");

  req.method = "GET";
  req.url = "/mystaticcontent.html";

  static(req,res,next);
}
