It happens because the action that took you to that page was a POST request. The browser wants to save you from unintentional double-ordering/paying/whatever when you go "back", when loading that page would need to do the form posted again.

How to work that around? I usually redirect the user to a page which was loaded by a GET request, it can be even the same page, see this answer: https://stackoverflow.com/a/3968038/357403
Or, you could modify the history: https://developer.mozilla.org/en-US/docs/Web/API/History_API

Also, please see the PRG pattern: https://en.wikipedia.org/wiki/Post/Redirect/Get

how to solve the issue in my above code. Please provide solution for this – user Oct 19 '15 at 07:49
What is the workflow? In which function do you enter? Where are you when you click "back", and which url it should be where the "back" goes back? (Please answer all 3) – Koshinae Oct 19 '15 at 07:53
$this->load->view('admin/home_page.php',$output,'refresh'); here is my problem – user Oct 19 '15 at 08:00

Try this code format:

$this->load->view('admin/home.php', 'refresh', $data);

or

redirect('home', 'refresh');
