Using a shared SSL certificate and page layout??

I am looking at a host who has a shared SSL certificate for its users. Is there a way to specify that when customers are checking out, and are entering credit card info, that it uses the SSL certificate?

How would this be done?

Also, when I look at my page of innerelement.cloudaccess.net/shop/catego...d-10/name-books.html how can I get a space between grey sections on both the vertical and horiz. layout?

I saw the posting about editing the files:


Display->Views and edit the file step of the view checkout for your template and add the code below after the first <?php in order to automatically redirect to your https URL:
Code:

if(strtolower($_SERVER) != "on"){
$app =& JFactory::getApplication();
$requestUri = $_SERVER;
if (!empty($_SERVER)) $requestUri = rtrim($requestUri,'/').'?'.$_SERVER;
$app->redirect('https://my_shared_ssl_url'.$requestUri);
}

Where is the template name that is being used defined in the settings? Since there are 2 different templates? And which file regarding the checkout needs to be modified???

Thanks
