title: Access current domain name on Application_Start
body: <p>Normally to access the current domain name e.g where the site is hosted I do something like </p>
  
  <pre><code>string rURL = HttpContext.Current.Request.Url.ToString().ToLower();
  </code></pre>
  
  <p>But <code>HttpContext</code> is not avaible on <code>Application_Start</code> only from <code>Application_BeginRequest</code>.</p>
  
  <p>Any ideas?</p>
