<p>I now changed my hosting to <a href="http://heroku.com">Heroku</a>.
I believe it will be far more reliable.</p>
<p>But as you should know my website is completely static.
I use <a href="http://nanoc.stoneship.org/">nanoc</a> to generate it.
But here is the conf to make it work on heroku.</p>
<p>The root of my files is <code>/output</code>. You only need to create a <code>config.ru</code><sup id="fnref:1"><a href="#fn:1" rel="footnote">1</a></sup> file:</p>

rack<span class="Keyword">-</span>rewrite

<p>Now, just follow the heroku tutorial to create an application&nbsp;:</p>
<pre class="twilight">
git init
git add .
heroku create
git push heroku master
</pre>
<p>Now I&rsquo;ll should be able to redirect properly to my own 404 page for example.
I hope it is helpful.</p>
