HTTPS

Got it. This is what I use on one of the most recent sites:

PHP Code:

if (isset($_SERVER['HTTP_HOST'])) {
    $config['base_url'] = (isset($_SERVER['HTTPS']) ? "https://" : "http://") . $_SERVER['HTTP_HOST'] . '/';
} else {
    // CLI tool
    $config['base_url'] = '';
} 


Not sure if it works on all configurations, but I get by on my local XAMPP and production server.

I guess long term it's not the most elegant solution, because it has to do a check and calculation for every request and it would be much better to just say base_url = X, but it works and probably doesn't affect the loads speed overall that much.
