title: ReturnURL does not contain the defaultURL file
body: <p>I am trying to determine why I am having an issue with forms authentication in my application.  Specifically the ReturnURL parameters.  I expect my URL to look like this      <code>"http://www.example.com/ApplicationName/login.aspx?ReturnURL=%2fApplicationDirectory%2ListImages.aspx"</code> when I browse to the address 
  <code>"http://www.example.com/ApplicationName"</code>.</p>
  
  <p>Web.Config contains</p>
  
  <pre><code>&lt;authentication mode="Forms"&gt;
    &lt;forms loginUrl="login.aspx" defaultUrl="ListImages.aspx" name=".WebDashboardAuth" /&gt;
  &lt;/authentication&gt;
  &lt;authorization&gt;
    &lt;deny users="?" /&gt;
  &lt;/authorization&gt;
  </code></pre>
  
  <p>The URL created is instead <code>"http://www.example.com/ApplicationName/login.aspx?ReturnURL=%2fApplicationDirectory%2"</code> and does not show the defaultURL file.</p>
  
  <p>What could be wrong with my setup?</p>
