<h3 id='req.originalUrl'>req.originalUrl</h3> <div class="doc-box doc-notice" markdown="1"> `req.url` is not a native Express property, it is inherited from Node's [http module](https://nodejs.org/api/http.html#http_message_url). </div>

This property is much like req.url; however, it retains the original request URL, allowing you to rewrite req.url freely for internal routing purposes. For example, the "mounting" feature of app.use() will rewrite req.url to strip the mount point.

js
// GET /search?q=something
console.dir(req.originalUrl)
// => "/search?q=something"

req.originalUrl is available both in middleware and router objects, and is a combination of req.baseUrl and req.url. Consider following example:

js
// GET 'http://www.example.com/admin/new?sort=desc'
app.use('/admin', (req, res, next) => {
  console.dir(req.originalUrl) // '/admin/new?sort=desc'
  console.dir(req.baseUrl) // '/admin'
  console.dir(req.path) // '/new'
  next()
})
