Kill session when user closes the browser

Hi,

We are using asp.net StateServer for asp.net session management. In our project we need to make sure that if a user is already logged in and if he is trying to acess the website from a different browser tab, we need to inform him that he is already logged in in another tab and use it instead of opening a new session. Consider the following scenarios:

1. User is logged on in tab1 and his session is still on, then user tries to logon from another tab, the browser sends the asp.net session_id cookie, In the page init i am checking if the Asp.net session Id cookie is present, if it is there i am checking if the it is a new Session (i.e. if the existing session timed out), if it is a new session then proceed with the user action else it means that the session in tab1 is still active so i am redirecting user to error page with appropriate message.

Now the problem with this approach is that, suppose session in tab1 is expired and user opens tab2 and performs some actions, now he goes back to tab1 and perform any action, i directly need to take him to log out page.

Please let me know how this can be achieved.

Hi,

We have the implement the following scenario in our application:

1. We use windows authentication. User opens our website in tab1 and does some action but with out clicking on save he opens a new tab tab2 and opens the same website again.
2. Now, if the user session in tab1 is active i need to warn users that the he is already logged on to application in some other browser and go to some log out page. But if the user session in tab1 is timed out then he must be able to continue with the website in tab2 as usual, but if he tries to do anything in tab1 he should go to session expired page.

I tried implementing it in following way.

1. I have a hidden field in each page which will be set to unique Id using GUID.NewID().
2. when user requests for a page the following code is executed.

3. if (Request.Headers["Cookie"] == null)
               {
                   //this means user is requesting hte page for first time.
                   //Generate a new GUID store it in session and also in the hidden variable on page.
                   Session["DefaultPage"] = Guid.NewGuid().ToString();
                   ((TextBox)page.FindControl("hiddenGUID")).Text = Session["DefaultPage"].ToString();
               }
               else if (Reque
   

This code was working before, but something has changed and I don't know what.  I have an anonymous registration page.  On it, I have a CAPTCHA image, with a URL pointing to an ASPX page that is generating the image.  On the Registration page I am generating a 6 digit code to be displayed in the CAPTCHA image, then saving it to a Session variable.  On the CAPTCHA ASPX page, I am grabbing that Session variable and creating the image.  However, the Session is resetting when the CAPTCHA ASPX page is called.  If I debug it, it has a different ID and the variable is gone.

Why is this happening and how can I fix it?  I have Sessions enabled in SharePoint 2007.

Hi,

I have a button control where I retreive 2 strings with 2 URL like in the code below.

What I wonder how it is possible to do, is how to open up 1 browser window with 2 Session Tabs where 1 Tab is http://www.google.com and the other http://www.yahoo.com

How can this be possible to do from code behind (C#)?

    protected void Button1_Click(object sender, EventArgs e)
    {
		String URL1 = "http://www.google.com";
		String URL2 = "http://www.yahoo.com";

		//How to open up a browser with two session tabs with each URL in each?
    }

I want my users to be able to open multiple browser tabs and be able to switch back and forth between them.  If Viewstate is saved for each page, I should be able to do this right?

Thanks,

Sam

Hi guys,

Really confused on this... let me explain the scenario.

i have a application on .net 2.0 .

once user is logged in, various session variables are stored for that users profile information (normal stuff). when user open a browser window and after doing some operation, closes the browser window directly.

and then reopen new window and try to access homepage of same application... he is presented with profile of the user which was logged in before (and widnow was shut down)

is this behaviour normal and common across all IE versions?

this behaviour is not consistent.... sometimes, its showing homepage of old user and sometimes its  showing login page (as if session is invalidated)

is there any way to abandon all session if browser window is closed (apart from capturing browser window close event)

hope i get some replies on this...
