How to configure osCommerce to work with SSL?

In order to configure osCommerce to work with SSL you should open the file /public_html/catalog/includes/configure.php and make the following changes:

define(‘HTTP_SERVER’, ‘http://www.yourdomain.com’); // eg, http://localhost – should not be empty for productive servers
define(‘HTTPS_SERVER’, ‘https://yourdomain.com’); // eg, https://localhost – should not be empty for productive servers
define(‘ENABLE_SSL’, true); // secure webserver for checkout procedure
define(‘HTTP_COOKIE_DOMAIN’, ‘www.yourdomain.com’);
define(‘HTTPS_COOKIE_DOMAIN’, ‘yourdomain.com’);
define(‘HTTP_COOKIE_PATH’, ‘/catalog/’);
define(‘HTTPS_COOKIE_PATH’, ‘/catalog/’);
define(‘DIR_WS_HTTP_CATALOG’, ‘/catalog/’);
define(‘DIR_WS_HTTPS_CATALOG’, ‘/catalog/’);

Similar to the above changes have to be made in the file /public_html/catalog/admin/includes/configure.php which is responsible for the admin area configuration.

In the above example we are configuring an osCommerce installation in the catalog directory with domain yourdomain.com. You should adjust the above settings to your details.

Note : Make sure to replace yourdomain.com with your actual domain name
