title: How do I include the original url as a request parameter, when proxying?
body: <p>I want to proxy the incoming requests with an nginx instance to a little java backend application. The idea is that I want every original request's uri to be included as a request parameter i.e. something like:</p>
  
  <pre><code>location / {
              proxy_pass http://localhost:9000?url=$request_uri;
          }
  </code></pre>
  
  <p>but it does not work</p>
