Preventing the Browser From Caching [ Help ]

You can't stop the back button from having this action depending on the browser you are using as from memory some browsers (IE6?) don't bother after refreshing content when you click back.

The real test is click back then press refresh and see if the status has changed. Alternatively if you are still having cache issues insert the following into the relevant controller function/method.

Code:

$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate, no-transform, max-age=0, post-check=0, pre-check=0");
$this->output->set_header("Pragma: no-cache");
