Can any body please help me.

1..When someone logs on set some variable. I assign their unique ID to a variable called EG session(ID")

2..When someone logs out call session.abandon (removes all session variable values)

3..Now in the HEAD of EVERY PAGE that requires the user to be logged in put something like:

<%
IF session("ID") = "" then
  'user is not logged in or has logged out
  response.redirect("somePage.asp")
END IF
%>

Dear birari ,

 Leave all the things .. make an ASP page page & include just these few lines
 Home.asp represents the desired page which should be opened after clicking the logoff button . give action of page to the page on which u are writing these lines ..

<% session.Abandon %>
<script>
open ("home.asp","_top")
</script>

I would use ASP's response object to redirect - why use a browser dependent method when you dont have to.

Sometimes (but most of the times) when you click back button page displayed will be from cache or temporary files. There is no specific solution for this because your cache will store the html content and it is not retrived from server. But when you click any other link it will say the session exipred message or redirect to login screen

hello there use this little code with the Session.Abandon to clear you privious link form the user.
use this :
<%
Session.Abandon
%>
<SCRIPT LANGUAGE="JavaScript">
window.location.replace ("home.asp");
</script>
it will replace your history back button with new location home.asp
