title: how can I test my facebook page tab app from localhost
body: <p>I'm developing a facebook page tab app. When I set page tab URL in app settings to something like <code>localhost/fbapp</code>, it doesn't work since the page tab is not simply iframe. Is there any workaround to resolve this?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I'm building facebook <strong><em>page tab</em></strong> with ASP.NET MVC-3.0 with fb C# SDK.</p>
  
  <p>What I've tried so far is to modify <code>hosts</code> file to point the URL I have on app settings to localhost(127.0.0.1). I've been testing facebook app in this way always but it doesn't work in facebook page tab.</p>
