What kind of authentication you use in your website?
Aravindbpanchu 1-Nov-12 22:37pm
authentication mode="Forms"

The following code will end session, sign out and redirect to login page as well as adding the page the user was on to the url as "?ReturnUrl=*.aspx"
'Do your "Is user logged in" check code here
' If not authenticated:
Reponse.End() '<-- IMPORTANT: the RedirectToLoginPage executes on server side but rest of code/logic also completes, so Response.End is required for FormsAuthentication.SignOut to work (a workaround).
Please refer to this article
How to end user session when browser closed[^]
Add Global.asax page:

add the following code in that file.
in the Application_End method clear all your session data

<![CDATA[<%@ Application Language="C#" %>]]>

<script runat="server">

    void Application_Start(object sender, EventArgs e) 
        // Code that runs on application startup

    void Application_End(object sender, EventArgs e) 
        //  Code that runs on application shutdown
        //  Clear Session Data here
    void Application_Error(object sender, EventArgs e) 
        // Code that runs when an unhandled error occurs


    void Session_Start(object sender, EventArgs e) 

    void Session_End(object sender, EventArgs e)

okay, after login page, you are navigating to another page. so in another page take a one session variable. when you press back button it will navigates to login page, so there check this session variable, if it is not empty or null, then display the expire content.
Login page:

  if(Session["AfterLogin"]!=null && Session["AfterLogin"]=="AfterLogin")
     //Your logic for login page.

in Another page: (afterlogin page)

  // your logic goes here.

i hope it helps you.

Then disable back button in browser.

in master page or ASPX page add onload event to body tag.
<body önload="history.go(+1);">

it will not redirect to back page.
Two Options, both already mentioned:

1) this.Session.Abandon(); or Session.Abandon();

2) System.Web.Security.FormsAuthentication.SignOut();

If both options are "already mentioned" what possible value does your "solution" add to this year old already answered question?
