Log out do not actually "log out" when click on back arrow (near the top of the IE toolbar)

Hi,

I use Visual Studio 2008, login controls in ASP.NET: loginview, loginstatus and login.  I use membership schema in sql server 2005 to store username and password.

Code Snippets:

login.aspx
<asp:Login ID="Login1" runat="server"
BackColor="#EFF3FB" BorderColor="#B5C7DE" Go to the complete details ...
