View 2 RepliesI have a web application build in asp.net and using a custom membership provider for authentication and authorization. Everything works fine except when the user click on the logout link to log out of the application and being redirect to a default cover page, if the use click on the BACK BUTTON on their browser, it will actually go back to where they were before and the data will still show up.
Of course they can't do anything on that page, click on anything link they will be redirect to a login page again. But having those information display is making a lot users confused.
i am just wondering if there is any way i can either clear the browser's history so use can't go BACK, or when they click on the back button and have them redirect to the login page.

Session.Clear();
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1D);

{
Response.Redirect("login.aspx");
}

i just like to ask if you have any idea of preventing the Back button of the browser to navigate back to the previous page after a user log in.Ex:After a user successfully logged in to my website and he/she hit the Back button of the browser.I want this to not redirected to the previous page instead redirected to the same page which is my Main page.Also after a user logged out to my website and again he/she hit the Back button of the browser.I also want this to not redirected to the previous page instead redirected to my login page.

I am trying to implement Login/Logout functionality in my website without using inbuilt functionality of Login controls in ASP.NET. In some pages, which require the user to be logged in, I have written this in Page_Load
if (Session["cod"] == null && Session["admin"] == null)
{
Response.Redirect("You need to Login.aspx");
}
if (Session["cod"] != null || Session["admin"] != null)
{
LinkButton1.Text = "Logout";
}
if (Page.IsPostBack == false)
{
log_bind();
grid1_bind();
grid2_bind();
}
But while I was testing this, I noticed that when I press the Back/Forward button on the browser, these pages are viewable without being logged in. How do I prevent this?

I have a website built in ASP.net 3.5, using WinForms and AjaxToolKit. I have encountered a lost/corrupt session issue while using Internet Explorer 8.
Scenerio:
1 IE8 Browser Open, 1 Tab
--------------------------------------
1. Login, Redirect to Landing, Logout - WORKS AS EXPECTED
2. Login, redirect to Landing, Close Window, Open Window, Logged-in already - WORKS AS EXPECTED (remember me enabled by default in code)
1 IE8 Browser, 2 Tabs
--------------------------------------
1. Login, Redirect to Landing, Open new tab, paste Landing page URL, Landing renders. - WORKS AS EXPECTED
- Logout from Tab 2, Tab 1 logs out after AJAX update. - WORKS AS EXPECTED
- Login from Tab 1, Redirects to Landing, then Redirects back to Login page - ISSUE
[code]...
2. Close Window,Login,Redirect to Landing - WORKS AS EXPECTED
2 IE8 Browser, 1 Tab
--------------------------------------
1. Open 2 IE windows
2. In Window 1, Login, Redirect to Landing, then Redirects back to Login. - ISSUE
- Window 2 Paste Landing page URL, Landing page renders - ISSUE, STRANGLY NOW WORKS
[code]...
This issue seems to only happen when I have multiple tabs open,or multiple rwssers open.Firefox and Chrome does not reproduce this issue and works as expected.How do I make sure the Cookie/Session is being handle correctly in IE8?
Here is my Login Auth:

Web.Config
