title: Reverse proxy with mod_proxy, preserve original request URL
body: <p>I've configured a reverse proxy using mod_proxy (Apache2) listening on 127.0.0.1:80, that proxies all the request to 127.0.0.1:8080</p>
  
  <p>So I've configured mod_proxy like:</p>
  
  <pre><code>ProxyPreserveHost On
  ProxyRequests Off
  ProxyPass /foo http://127.0.0.1:8080
  ProxyPassReverse /foo http://127.0.0.1:8080
  </code></pre>
  
  <p>When I request <code>http://127.0.0.1/foo/bar</code>, the app listening on 127.0.0.1:8080 gets the following request URL from mod_proxy:</p>
  
  <p><a href="http://127.0.0.1/bar" rel="noreferrer">http://127.0.0.1/bar</a></p>
  
  <p>Instead I'd like to preserve the original request, and get:</p>
  
  <p><a href="http://127.0.0.1/foo/bar" rel="noreferrer">http://127.0.0.1/foo/bar</a></p>
  
  <p>How can I do this?</p>
