Web.config and timeout

[hpl]

I have set a timeout in my web.config to 20 min. I wish that the user is redirected to the login-page (login1.aspx) when timing out. But this doesn't happen applying the web.config file shown below. What is wrong?

<?xml version="1.0" encoding="utf-8" ?>

          false at all other times. For more information, refer to the documentation about
          debugging ASP.NET files.

I forgot to import system.web.security on all pages

[nemaroller]

??

How does importing Web.Security handle this?

[venerable bede]

Yeah. How does that work for you ?

[hpl]

in the .vb file you include this:
Imports System.Web.Security

And I have used these tags in the web-config file:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    
  <system.web>
	
	<!--<pages smartNavigation="true" />-->

          false at all other times. For more information, refer to the documentation about

mmm... Importing System.Security just tells the compiler to make that class reference available to your page.

It (the reference) isn't necessary to redirect a user to the login page when they timeout, because it doesn't accomplish anything.
The web.config for that application accomplishes redirection if the session times out.
