Rails - Nov 2005 - Login Authentication working in IE but not in Mozilla

I have gone through the following site for the creation of my login 
page:
To mention I am using Windows XP pfofessional running on WEBBrick server

http://wiki.rubyonrails.com/rails/pages/HowtoAuthenticate

The code is given in the following 3 steps:

1)The controller that needs protection:

class WeblogController < ActionController::Base
  before_filter :authenticate

  def index
    # show the secret stuff
  end

  protected
    def authenticate
      unless @session["person"]
        @session["return_to"] = @request.request_uri
        redirect_to :controller => "login"
        return false
      end
    end
end

2)The controller that does login:

class LoginController < ActionController::Base
  def index
    # show login screen
  end

  def authenticate
    if @session["person"] =
Person.authenticate(@params["name"],
@params["password"])
      if @session["return_to"]
        redirect_to_path(@session["return_to"])
        @session["return_to"] = nil
      else
        redirect_to :controller => "weblog"
      end
    else
      flash["alert"] = "Login failed!"
      redirect_to :action => "index"
    end
  end

  def logout
    reset_session
    flash["alert"] = "Logged out"
    redirect_to :action => "index"
  end
end

3)The model that does authentication:

class Person < ActiveRecord::Base
  def self.authenticate(name, password)
    find(:first,
      :conditions => [ "name = ? AND password =?", name, password ]
    )
  end
end

 My problem is that the above code works properly in Internet Explorer 
browser but fails to work in Mozilla browser. What I mean to say is that 
once I logout using a link_to in my home page I call the logout function 
in my login controller and reditrect to my login or index page. Now if I 
click on the back button, it still takes me to the home page. This 
should not happen as the session has already been destroyed. In Internet 
Explorer, there''s no problem at all. In IE if I click the back button 
after logging out it redirects me to the index page and not to the home 
page.
    Kindly help me out in this regard..
Thanks and regards..
