title: Nginx proxy_pass location absolute paths
body: <p>I had a proxied page: <code>http://destsrv:8089/index.html</code>
  It contains link to absolute path like: <code>href="/static/bootstrap/css/bootstrap.min.css"</code></p>
  
  <p>And nginx is configured like:</p>
  
  <pre><code> location /admin/ {
                proxy_pass http://destsrv:8089/;
          }
  </code></pre>
  
  <p>Although when accessing the <code>http://myproxy/admin/index.html</code>
  it is trying to get .css from:
  <code>http://myproxy/static/bootstrap/css/bootstrap.min.css</code></p>
  
  <p>But expected is:
  <code>http://myproxy/admin/static/bootstrap/css/bootstrap.min.css</code></p>
  
  <p>How to do it?</p>
