+In case you haven't noticed, nowhere have we written any logic that returns different data depending on the path of the request. As such, our simple HTTP server responds to every path the same. For example: [http://localhost:8080/path/to/file/one](http://localhost:8080/path/to/file/one) and [http://localhost:8080/path/to/file/two](http://localhost:8080/path/to/file/two). Experiment with `req.url` to see if you can route requests based on the resource requested. Another useful module is [url](http://nodejs.org/api/url.html).
