express/connect middleware which executes after the response is sent to the client

Is it possible to write a middleware which executes after the response is sent to a client or after the request is processed and called just before sending the response to client?

pauljz gave the basic method but to expand on that here is an example of middleware

module.exports = function() {
  return function(req, res, next) {
    req.on("end", function() {
      // some code to be executed after another middleware
      // does some stuff
    });
    next(); // move onto next middleware
  }
}

In your main app

expressApp.use(require("./doneMiddleware"));
expressApp.use(express.logger());
expressApp.use(express.static.....

See if binding to req.on('end', function() {...}); will work for you.
