Checkout over SSL, but no other pages

[zq29]

Hi guys,

 

I am trying to ensure that only the checkout page of a website is forced through an SSL connection with mod_rewrite. Here are some relevant bits from my .htaccess file:

 

RewriteEngine On
RewriteBase /
Options FollowSymLinks

RewriteCond %{SERVER_PORT} ^443$
RewriteRule !^checkout\.html$    http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

RewriteCond %{SERVER_PORT} ^80$
RewriteRule ^checkout\.html$    https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

#snip...
RewriteRule ^checkout\.html$    index.php?page=checkout&%{QUERY_STRING}
RewriteRule ^([a-z_]*)\.html$    index.php?page=$1
#snip...

 

Now, when I browse to http(s)://www.domain.com/checkout.html, my address bar points to http://www.domain.com/index.php?page=checkout and then appears to get stuck in an infinite loop.

 

I've been messing with it for a while now and can't figure it out, does anyone have any ideas?
