Description
Redirects to another controller and action after disabling HTTP caching.
The _redirect() method is often called after a successful POST operation, to show a "success" or "edit" controller. In such cases, clicking clicking "back" or "reload" will generate a warning in the browser allowing for a possible re-POST if the user clicks OK. Typically this is not what you want.
In those cases, use _redirectNoCache() to turn off HTTP caching, so that the re-POST warning does not occur.
This method sends the following headers before setting Location:
<?php
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
