ASP.Net logout code block

问题

I need a good logout code block for asp.net. Currently after you logout you can hit the back button and continue using the site.

回答1:

You need to make sure that the session is abandoned and call the FormsAuthentication.SignOut() method as shown below:

private void Logout()
{
  Session.Abandon();
  FormsAuthentication.SignOut();
  FormsAuthentication.RedirectToLoginPage();
}

回答2:

Assuming you're using Forms Authentication, you would just do:

System.Web.FormsAuthentication.SignOut();

Without more information I can't be more specific.
