Question

I am working with a Login Page(using c#, visual studio 2008). In which a user have to enter Name and Password.

After clicking on Login, it will redirect to Home Page.. Now, if i click on Logout, it is redirecting to Log in Page. It’s fine till now.

My issue is, at this moment(after logged out) if i press Back button it is again taking me to Home Page.But, Here i want to get a message saying that

You are already logged out. Please Login again

it should not allow me to access Home page.

How to do it…?

Answer 1

use this code:

protected void logout_OnClick(object sender, EventArgs e)
{
Session.Abandon();
Response.Redirect("login.aspx");
}

protected void Page_Init(object sender, EventArgs e)
{
Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
}
