How to ensure that Apache always serves a single page via HTTPS?

I would like to redirect all connections from htt_p://www.example.com/abc.html to HTTP_S://www.example.com/abc.html . What mod_alias or mod_rewrite commands would work for this? I've tried:

RewriteEngine on
RewriteCond %{HTTPS} =off
RewriteRule $abc\.html^ https://www.example.co开发者_开发知识库m/abc.html [R]

in both .htaccess and httpd.conf but that doesn't work. It works if the first string in the RewriteRule is anything else (like abz.html) but not if it is abc.html. abc.html is a real file on the server (not another redirect). Options FollowSymlinks is present in the appropriate Directory directive.

Many thanks.

Something along the lines of the following will allow you to redirect non-SSL pages to SSL versions (assuming that you are running SSL on port 443):

RewriteEngine on

# Limited redirects
RewriteCond %{SERVER_PORT} !^443$
RewriteCond %{REQUEST_URI} ^/abc\.html$ [OR,NC]
RewriteCond %{REQUEST_URI} ^/def\.html$ [OR,NC]
RewriteCond %{REQUEST_URI} ^/ghi\.html$ [NC]
RewriteRule ^/(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

The [OR] flag after the RewriteCond is literally that, "or", which is why the last condition doesn't have it
