Codeigniter-SSLHook

This hook will automatically redirect to the HTTPS version of your website and set the appropriate headers.

Installation

Make sure your base_url starts with https

Copy /application/config/hooks.php into your application's folder. If you have other hooks copy the content of /application/config/hooks.php to your hooks.php file.

Enable hooks by modifying your /application/config/config.php, set enable_hooks to TRUE:

/*
|--------------------------------------------------------------------------
| Enable/Disable System Hooks
|--------------------------------------------------------------------------
|
| If you would like to use the 'hooks' feature you must enable it by
| setting this variable to TRUE (boolean).  See the user guide for details.
|
*/
$config['enable_hooks'] = TRUE;

How does it work?

The hook will:

• Redirect to the HTTPS version if accessed from a non-secure connection.
• Make cookies only accessible via HTTPS (no JavaScript)
• Set the following headers:
  • Strict-Transport-Security: max-age=2629800
  • X-Content-Type-Options: nosniff
  • Referrer-Policy: strict-origin
  • X-Frame-Options: DENY
  • X-XSS-Protection: 1; mode=block
