title: Determine the URL hostname without using HttpContext.Current?
body: <p>Using the current request I can get the URL hostname with:</p>
  
  <pre><code>HttpContext.Current.Request.Url.Host
  </code></pre>
  
  <p>But - I need to determine the URL hostname without using the current request (<code>HttpContext.Current</code>). The reason for this is that my code is called from a <code>SqlDependency</code> in the onChange callback for when a SQL Dependency is found. Althougth the code resides in my web app, there is no request, and <code>HttpContext.Current</code> is null.</p>
  
  <p>I was hoping I could grab it from <code>HttpRuntime</code>, but there doesn't seem to be anything of use there. is there a way I can get this information?</p>
