  1. When the installer runs it calls wp_install(), that in turn calls populate_options() defined in wp-admin/includes/schema.php, which runs the following..

    if ( !__get_option('home') ) update_option('home', $guessurl);

    Prior to that $guessurl is defined by..

    $guessurl = wp_guess_url();

    The guess URL function is defined in wp-includes/functions.php and looks like this.

    function wp_guess_url() {
    if ( defined('WP_SITEURL') && '' != WP_SITEURL ) {
        $url = WP_SITEURL;
    } else {
        $schema = is_ssl() ? 'https://' : 'http://';
        $url = preg_replace('|/wp-admin/.*|i', '', $schema . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    }
    return rtrim($url, '/');
}

    Hope that’s the info you’re looking for… 🙂
