title: Nginx request_uri without args
body: <p>How do I get the value of <code>request_uri</code> without the args appended on the end. I know there is a <code>uri</code> variable but I need the original value as the Nginx documentation states:</p>
  
  <p><strong>request_uri</strong></p>
  
  <blockquote>
    <p>This variable is equal to the <em>original</em> request URI as received from
    the client including the args. It cannot be modified. Look at $uri for
    the post-rewrite/altered URI. Does not include host name. Example:
    "/foo/bar.php?arg=baz"</p>
