title: After doing FormsAuthentication.SignOut(), user is not able to login again
body: <p>I am using formAuthentication with the following Web.Config file.</p>
  
  <pre><code>&lt;authentication mode="Forms"&gt;
      &lt;forms name="SnowBall" timeout="30" slidingExpiration="true" loginUrl="Login.aspx"      cookieless="AutoDetect"&gt;
      &lt;/forms&gt;
  &lt;/authentication&gt;
  &lt;authorization&gt;
      &lt;deny users="?"/&gt;
  &lt;/authorization&gt;
  </code></pre>
  
  <p>I have a user control which has a LogOut button. Code of the logout button is:</p>
  
  <pre><code>FormsAuthentication.SignOut();
  Response.Redirect("Login.aspx");
  </code></pre>
  
  <p>After executing this code, I am no longer able to authenticate the user. When i click "Sign In", the page is refreshed and event handlers are not executed.</p>
  
  <p>When I close the browser window and re-run the site, everything works fine. Please help me.</p>
