Session variable
I use Session variable to check if the user have login or not. I would like to detect if the seeion has expired. if so re-login is required. I write the following code, but I did work as expected. It seems like (Session("member_id") != "undefined") is always true, even though it is equal some number. Can you tell me what is wrong with my code? and how to get it working.
<%@LANGUAGE="JAVASCRIPT"%>
<%
if (Session("member_id") != "undefined") {
Response.Redirect("login.a
}
%>
<html>
<head>
<title>Brisbane Car Pooling Services</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

Response.Redirect("login.a
}

Meng,
Is this client-side or server-side code? I don't think that this will work client side. If it is server-side code, are you programming in JavaScript, JScript, or VBScript?

fritz, he is using JScript Server-Side as evidenced by the language value. I use JScript also on the server-side.
Brandon,
Fair enough--it's just that the first line of code that he wrote was: <%@LANGUAGE="JAVASCRIPT"%>
I just wanted to make sure that I understand what's going on before I chimed in.

Are you sure it's getting set correctly?

hi b1xm12,
Yeap. I set the session variable the first time the user login. and in any other asp pages, the session variable is still there with the correct value. But when I go in login asp page, the session variable become undefined.
anything special about my login.asp page? I use Dream Weaver UltraDev 4.0.

Is there a directive like the EnableSessionState ?
<%@language="JScript" @EnableSessionState="False
This will cause no Sessions to be available.
Or This somewhere in your Script
<%
Session.Abandon();
%>
<%@language="JScript" @EnableSessionState="False

Session.Abandon();

if(val) evaluates to
numbers: null, < 0, undefined => false
strings: null, '', undefined => false
in Microsoft JavaScript.
So my suggestion would be:
if(!Session("member_id"))
Response.Redirect("login.a
numbers: null, < 0, undefined => false
strings: null, '', undefined => false
in Microsoft JavaScript.
So my suggestion would be:
if(!Session("member_id"))
Response.Redirect("login.a
This question has been abandoned. I will make a recommendation to the moderators on its resolution in a week or so. I appreciate any comments that would help me to make a recommendation.
In the absence of responses, I may recommend DELETE unless it is clear to me that it has value as a PAQ. Silence = you don't care

The above check will be true if session expires.
