redirect http to https

[alina]

Hi everybody,
I have a small issue.
How do I redirect
http://shop.com/products/index.php?main_page=login
to
https://shop.com/products/index.php?main_page=login

After I've googled it a few times, I've tried to write the following code in an .htaccess file in the products folder, but it doesn't work. The SSL is on, but there must something wrong with the code I wrote.

Options +FollowSymLinks
Options -Indexes
ServerSignature Off
RewriteEngine on
RewriteBase /

RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} products/index.php
RewriteRule ^(.*)$ https://www.shop.com/products/index.php?main_page=login$1 [R,L]

I'm dummy with .htacess files, so any help would be apreciated.
Thatnks.

do you have SSL installed ? if so , you need to modify your configure.php files to enable SSL . Zencart is smart cart , will redirect to SSL ( https) for needed pages , such as your login page.
