Lost session variables

google · Feb 1, 2007

I have a website that has a asp secured members only aria that keeps
session variables to check if someone is logged in or not (if session
variables are not there then redirect to logon screen) but I also have
non members aria and I need a way of asking the user if they want to
move away from the members only aria or go back to it. I have used an
asp to find out if the page is a non member page and if there is a
session variable there. If there is a session variable and is a non
member page then I use JavaScript to bring up a confirm box that if
the cancel button is pressed then it goes back a page. The problem is
that when you go back a page the session variable gets lost. Dose
anyone know how to solve this problem or a better way of doing this?

Better show your asp code, only the relevant part, that is.

If you loose the session, you loose the session variables,
so I think it is about losing the session.

The page you come from is or should be stored in:
Request.ServerVariables("HTTP_REFERER")

here is my code
logon is set to 1 in a include that is only on member pages

<%if logon<>1 then
if session("user_ID") <> 0 OR Session("user_ID") <> "" then
%>

<script type="text/javascript">
var r=confirm("are you shure you want to leave the secure area?")
if (r==true)
{
}
else
{
history.go(-1)
}

</script>
<% end if
else %>
a members menu bar include
<%end if %>

This boolean is always true!!!!

The boolean can only be false,
if session("user_ID") is both 0 and "" at the same time,
which is impossible.

Are you sure? What if Session("User_ID") is empty?

This code would be better:-

If Session("User_ID") = Empty Then
