Forced SSL sometimes not working

-- HikaShop version -- : 2.2.3
-- Joomla version -- : 3.2.1
-- PHP version -- : 5.3.3

I guess this is not a problem but a bug because I have tested it explicitly. Let me explain the settings:

1) Hikashop > System > Configuration > Checkout > Force SSL on checkout = YES
2) Setup a module using "Mini Cart = YES " and "Show proceed button in the cart = YES"
3) Place the module with all pages, include pages that outside the Hika shop (eg: Zoo, Jomsocial, etc)

Problem:
I found when I click the [CHECKOUT] button in the Mini-cart Moudle, especially while displaying screens outside Hika Shop, the SSL (https://) won't show up in some occasion.

I have tested it explicitly with menu "Meta Data > Secure = Ignore or Off" (on other pages) but the problem persist sometimes without any pattern (sometimes https:// show up and sometimes not), even with the "Force SSL on checkout = YES"

Please advise if this is any kinds of setup problem or bugs as this may greatly affect customer experience, because if https:// sometimes not show up with checkout, customer feel unsecure.

Thanks.

Hi Hikashop,

Your suggestion could be one solution but in Joomla 3.x, they have provide Menuitem> Metadata > Security = YES to force a page / menu item to be loaded in https (SSL). However, even I have created a menu item for "Checkout", the same is not guarantee in https:// while going thru the [CHECKOUT] button with the minicart module.

Actually I do not want to add any 3rd party SSL redirection module with my site, especially I've seen a lot replies from the post your recommended me to read, said some of them CRASH their site after installing that components.

Please advise if any workaround within Hikashop (like, force the URL to https:// while passing thru URL via minicart) or it's something I can wait with Hikashop update?

I have just done a small test: this problem only exist WHEN the minicart=YES. Is there any programming issue with minicart=yes while handling https:// url? or loading the Force SSL on checkout = YES parameter?

Hi Nicolas,

I tried the customization with the 'Display > Views', (My template), Products, cart ... (on Line 119), however, the problem still there. Do you know what is the reason that may cause the problem? (eg: Falang (Multi-lang environment)?) or possibly the .htaccess file?

Actually I am still quite wonder why MINICART=NO and it works normally all the time.
but when MINICART=YES and it will fail loading https sometimes.

Thanks Nicolas,

Can you confirm this is the correct item: 'Display > Views', (My template), Products, cart ... (on Line 119)' ?

I found the URL of the button does not modify after the view override:
<input type="submit" class="btn button hikashop_cart_input_button" name="checkout" value="結帳" onclick="var field=document.getElementById('hikashop_product_quantity_field_1');window.location='/main/zh/component/hikashop/checkout';return false;">
(the both http:// and https:// and www.mydomain.com did not appear, the html code just use the relative url)

but, the MINICART=NO part, the button changed with the modification :~) , I guess I found the incorrect code:
<input type="hidden" name="url" value="http%3A%2F%2Fwww.mydomain.com%2Fmain%2Fzh%2Fmarketplace%2Fhome">

Anyway, I found this possible part and don't know how to modify...
