ASP MVC allow static html files
<p>I have a simple ASP MVC project. 
Under this site I need to show plain .html files, without treating routes as <em>controller/action</em>.</p>

<p>I have folder <em>documentation</em> with file <em>index.html</em> in it.
I need to have this accessible under <em>www.mydomain.com/documentation</em>, it returns 403.
Currently it works only under <em>www.mydomain.com/documentation/index.html</em> </p>

<p>I have added         </p>

<pre><code>routes.Ignore("developers/");
</code></pre>

<p>into <code>RouteConfig.cs</code></p>

<p>and in <code>Startup.cs</code> for OwinAppBuilder</p>

<pre><code>        app.UseStaticFiles();
</code></pre>

<p>What should I do to have it accessible under <em>www.mydomain.com/documentation/index.html</em> ?</p>
