I'm using drupal 6 and already sets SSL Certificate (with my own Certificate Authority (CA) ) configuration of my apache server. And added following redirection in drupal .htaccess file

RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^test/home https://localhost/test/home [R=301,L]

When I try to access http://test/home it redirects to https://test/home correctly but it results following 404 Error

Not Found

The requested URL /test/home was not found on this server. Apache/2.2.9 (Ubuntu) PHP/5.2.6-2ubuntu4.6 with Suhosin-Patch mod_ssl/2.2.9 OpenSSL/0.9.8g Server at localhost Port 443

And Moreover secure pages module doesn't allow to enable it shown as below

Is there any configuration problem ? please guide me.
