Question

I have created a web application using ext.net and c# in visual studio 2010. When the user click on the about button, the about window is displayed from the index page. In web.config file I have following code:

<authentication mode="Forms"> 
  <forms loginUrl="~/Login.aspx" protection="All" defaultUrl="~/Login.aspx" timeout="2000"/>
</authentication>  

My problem is that, when the session is expired and the user click on the about button, the login page is displayed inside the about window. I have to refresh the page manually to redirect to the login page. I don’t want the login page display in the about window when session is expire. Any help?

Thanks in advance!

Answer 1

Put the below javascript in the login page head section

<script>
if(self!=top)
 top.location.href=window.location.href;
</script>

self means the current window, that will become the window inside the frame. top means the top most window. that is the browser window. So if top!=self means if the current window is not the topmost window
