How to configure Nginx as reverse proxy server?
<p>I try to create proxy server using Nginx.</p>

<p>I need configure Nginx that if I request any URL address as client, Nginx must return this URL page immediately. For example I request page using param <code>url</code> from my server:</p>

<pre><code>http://myserver.com/url=www.gogo.com
</code></pre>

<p>Nginx should return me page <code>www.gogo.com</code></p>

<p>I tried in location:</p>

<pre><code>proxy_pass $host
</code></pre>
