'it didnt work for me' is not enough. Elaborate. Share some code if required.

In the logout.aspx.cs page i used the following code:
protected String m_TargetPageTxt = "";
protected void Page_Load(object sender, EventArgs e)
{
Session.Abandon();
m_TargetPageTxt = "Login.aspx";
}


and I used the JS in logout.aspx source as

<script language="javascript">
var TargetPageTxt = '<%=m_TargetPageTxt%>';
if (TargetPageTxt != "") {
window.top.navigate(TargetPageTxt);
}
</script>

It goes to the login page when i click logout but the session variables are not cleared in all the pages.

Session.Abandon() and Session.Clear() are different methods.
session.clear() will clear session value not remove the session from memeory. where .Abandon() is removes all session from memory.

may be your session.abandon worked but session not refreshed, try the following

IE settings Toos Menu --> Internet options --> Setting (under browser history) --> select "Everytime i visit to the page" --> close the browser and try again

Just remember that you will never always sit on each client computer to manually clear their browser history. I would suggest a way to achieve this programmatically, not manually.
How about setting your session variables to null?
like so:
C#
//clear
Session[ "id" ] = null;
Session[ "password" ] = null;

//check
if(Session[ "id" ] != null && Session[ "password" ] != null)
{
   //user is logged in
}
else
{
   //user is not logged in
}


Happy coding,
Morgs
   
CSS
Try this
At logout
Session["sessionname"]= "";
