title: ASP.NET Forms Authentication - Too many redirects
body: <p>I have an ASP.NET 4.5 webforms site and trying to setup forms authentication.  I have an Account folder with a Login.aspx page within.  The main web.config contains the following:</p>
  
  <pre><code>&lt;authentication mode="Forms"&gt;
    &lt;forms loginUrl="~/Account/Login.aspx" timeout="2880"/&gt;
  &lt;/authentication&gt;
  &lt;authorization&gt;
    &lt;deny users ="?" /&gt;
    &lt;allow users = "*" /&gt;
  &lt;/authorization&gt;
  </code></pre>
  
  <p>When I browse to the site, it appropriate redirects to <code>Account/Login.aspx</code> and then throws a browser error indicating </p>
  
  <blockquote>
    <p>Too Many Redirects</p>
  </blockquote>
