Back button and caching - El Forum - 06-17-2011

Hi,
I have a problem related to BACK button in browsers.
In very first page my basket shows "0 item". I go to next page to add one item to basket $this->cart->insert($data) and it shows $this->cart->contents() "1 item" in current page. If I hit BACK button in browser to go back to very first page again, the basket shows "0 item" although the basket has actually "1 item" in it. So, how do I solve this problem? Is it related to cache or refreshing etc. I read a bit about caching but I lost myself in it also not sure it is to do with it anyway.
Is there anything I can do with CI functions? Placing a code on top of the page or caching bits....
Thanks for advance

This has been answered quite many times before in these forums. Do a little search.

To be honest with you, I did some search and left same message to other forms but no luck.

Got the answer from another forum.
Code:
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
$this->load->view('template.php', $data);Back button and caching - El Forum - 06-17-2011

Hi Lab Assistant, I even have more response from another forum!
Thanks Sr. Research Associate.
Code:
public function stop_caching()
{
$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0");
$this->output->set_header("Pragma: no-cache");
//** PHP Style
//header("Cache-Control: no-cache, no-store, must-revalidate, post-check=0, pre-check=0");
//header("Pragma: no-cache");
