title: codeigniter authentication: redirecting to home page
body: <p>I am new to codeigniter framework. I am trying to build a authentication system.</p>
  
  <p>Authentication is working fine. My problem is that after successfully logging, when I click the back button in the browser it is directed to login page again. I want to redirect it to the home page itself.
  i want to reload the home page not the index page(index page is the login page, after successful login goes to home page)</p>
  
  <p>How can I do it</p>
  
  <p>Thanks in advance</p>
