ModRewrite VirtualHost and SSL

Hello,

I'm trying to configure mass virtual host based on mod rewrite (per Apache
2.0 documentation: http://httpd.apache.org/docs-2.0/vhosts/mass.html), and
basic functionality works. However, the SSL pages cannot be served. It
appears to searching pages in the /var/www/html, ... (per ssl_error_log).

Here is a sample of httpd.conf file:
--
RewriteEngine on
RewriteMap lowercase int:tolower

# define the map file
RewriteMap vhost txt:/var/www/html/vhost.map

# deal with aliases as above
RewriteCond %{REQUEST_URI} !^/icons/
RewriteCond %{REQUEST_URI} !^/cgi-bin/
RewriteCond ${lowercase:%{SERVER_NAME}} ^(.+)$
# this does the file-based remap
RewriteCond ${vhost:%1} ^(/.*)$
RewriteRule ^/(.*)$ %1/$1

RewriteCond %{REQUEST_URI} ^/cgi-bin/
RewriteCond ${lowercase:%{SERVER_NAME}} ^(.+)$
RewriteCond ${vhost:%1} ^(/.*)$
RewriteRule ^/(.*)$ %1/cgi-bin/$1
--
The /var/www/html/vhost.map contains the rewrite rule, i.e.
--
www.helloworld.com /home/someuser/www.helloworld.com
--

Now, How do I configure the Apache to serve https pages as well as the http?
Thanks.
